Tue Jul 24 20:21:31 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * make a copy of the data required for solution viewing
  
  this is necessary because when the solver is running it might delete
  the currently visible solution and then moving the animation slider will
  crash the program. Now we have a private copy and nothing will go wrong

Tue Jul 24 20:21:04 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * free the assembler thread, when closing the window

  * do piece hiding in solution view only when shift is pressed

Wed Jul  4 20:46:17 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * prevent division by zero error when grid is much bigger than the grid editor
  
  the function that calculates the position within the grid can now return false
  which means that no coordinates can be calculated

Sun Jul  1 12:54:52 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * part 1 of Joe Beckers editing suggestions for the documentation

Mon Jun 25 20:26:16 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * better heurisitc for guessing with which column to continue in assembler 1
  
  this can result in quite some speedup (I've seen 3 times) but it still is just
  a heuristic and not mathematically founded. We do need something better in there

Mon Jun 25 17:02:52 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * add function to sort solution by used pieces, also optimize solver button matrix a bit

Fri Jun 22 17:14:51 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix range optimisation
  
  the sometimes the no range pieces already take up more voxels than there are
  fixed voxels, so the minimum range might be negative, this is not possible so
  raise that value to 0

Fri Jun 22 13:42:26 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * better space utiliation in problem view, now measuring the size of the result independent from pieces

Fri Jun 22 11:14:07 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * optimize block list drawing to only draw visible blocks
  
  this speeds up drawing of lists with very many blocks that are mostly invisible

Fri Jun 22 10:41:08 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * change the new editor behavior
  
  now rotation is unchanged to the old sw
  - shift click adds a normal voxel
  - alt click adds a variable voxel
  - ctrl click removes a voxel
  
  the other views select or hide pieces by clicking at them

Fri Jun 22 09:50:11 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * solving and editing solution now also counts as changed and will result in asking to save when quitting

Sun Jun 17 21:23:20 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * openGL test only for non mingw32 systems

Sun Jun 17 11:03:59 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix hit searching, the last hit was not evaluated resulting in sometimes the wrong hit returned

Sun Jun 17 08:59:29 CEST 2007  Andreas Röver <roever@users.sourceforge.net>

Sat Jun 16 22:06:24 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * skip everything in the Select buffer that has not 3 name entries, necessary for the 3 axes

Sat Jun 16 21:52:01 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * add shape selection via 3d in problem tab and piece hiding via 3d in solution tab

Sat Jun 16 21:32:46 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * add left mouse click callback to 3d widgets and implement adding by clicking
  
  it is now possible to add voxels by clicking onto the faces of exising voxels
  normal left click adds normal voxel
  shift left click add variable voxel
  ctrl left click removes voxel below mouse

Sat Jun 16 21:31:07 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * add a function to voxel space to scale the space so that a given point can be included
  
  this point may be negative or everywhere else, the whole space is shifted so that
  the (now shifted too) point is within the available space

Sat Jun 16 19:32:13 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * implement face selection for triangles and spheres

  * add a check for openGL libraries and properly connect the strings for the pthreads

Thu Jun 14 16:45:40 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  tagged 0.3.0

Tue Jun 12 16:44:33 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * pthread c flags mut also be applied to linking

Thu Jun  7 21:27:58 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix comment from last comit

Thu Jun  7 16:30:04 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * make image export and display use the same perspective call

Wed Jun  6 21:33:20 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * Huge improvements to the image export layouting method
  
  - the final image size is better guessed by not adding a border when minimizing, but rather add a final image size
  dependend gap between the images
  - the layouter no longer works with a growing number of lines but with a decreasing hight of a row, this results in
  better utilisation of available space because a 1 pixel flater row might result in a fit, while the old method has to add
  a whole new row

Wed Jun  6 21:31:00 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * Use tiles when grabbing OpenGL images, this seems to be more stable (at least it works in my computer)

Tue Jun  5 20:10:41 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * use only the first solution, when enabling options in image export as other solutions can not be selected

Tue Jun  5 20:10:12 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * disable the image export menu entry, when there is nothing to export

Sun Jun  3 21:12:14 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * the image export now updates the available output options when a new problem is selected
  
  this is necessary because different problems have different solving state

Sun Jun  3 18:23:53 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * implement assembly and disassembly image sequences for image export

Sat Jun  2 16:18:45 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * when in debug mode the program prints texts explaining what is going on

Sat Jun  2 16:18:17 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * calculate the number of columns and rows removed by the matrix optimisation

Sat Jun  2 16:11:23 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * add a counting optimisation
  
  the idea behind this is that if we have piece ranges and fixed pieces to place we do know
  how many voxels can be contributed by range pieces. An example, 10 piece with 6 cubes plus
  one 4 cube piece shall make a 4x4x4 cube. We want to try all different 4 cube pieces possible.
  This is done by adding all 4 cube pieces with a 0-1 range.
  Without the optimisation the programm will add several of the 4 cube pieces because there still
  are more than 10 placements for the 6-unit pieces.
  Now we add an additional column that contains the number of missing cubes as condition (in the
  example 4) and a weight for each of the range pieces that is equal to the number of units that
  piece is made of (again 4 in this example).
  The result is that the program will not add more range pieces than are possible due to the number
  of units the result has.

Fri Jun  1 17:58:40 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * set version to 0.3.0 for next release

Wed May 30 21:36:48 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * load system colors, also add a small space at the right for the OSX window resizer

Wed May 30 21:22:31 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * update documentation with piece ranges and the interface changes

Wed May 30 17:44:38 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * in problem detail editor the maxHoles input is only available, when there are piece ranges

Wed May 30 17:04:16 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * copy constructor for problem didn't copy the new maxHoles member

Wed May 30 17:01:13 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * missed to initialize maxHoles in problem when creating a new one

Wed May 30 17:00:36 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * the problem detail editor is always available, even if no piece is in problem

Wed May 30 17:00:10 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * give the shape and problem selector a bigger minimum size

Wed May 30 16:59:45 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * the problem detail editor needs a redraw after edit, because min and max might change one another

Wed May 30 16:59:12 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * the last change to the 6-piece burr example saved only 100 solutions

Tue May 29 17:12:05 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix a gap in the color constrain editor visible on windows

Mon May 28 17:46:31 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * add functionality to define the maximum number of holes alowed
  
  this is only usable in puzzles with piece ranges as in all other puzzles the number
  of holes (not occupied variable voxels) is fixed and calculatable

Mon May 28 15:14:54 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * groups editor is now also using the layouter

Mon May 28 13:00:55 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * implement hole optimisation for assembler 1
  
  this counts the number of holes alowed in an assembly and always checks if there
  are already more unfillable columns in the final assembly

Mon May 28 12:59:25 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * cleanup for debug interface and implement is for assembler 1

  * implement saving and restoring of state for the new assembler 1

Sat May 26 11:01:51 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fall through in the big switch in assembler 1 iterative function wherever possible to prevent unneeded looping

Sat May 26 11:01:27 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * remove the disassembly instructions from solid 6-piece file

Sat May 26 09:00:00 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * update the setup and 100% finished calculation to properly work

Wed May 23 21:15:15 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * update the NEWS file a bit

Wed May 23 21:00:14 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * groups editor is now the problem detail editor

Wed May 23 20:52:06 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix "-1" piece button, we need to first decrement min counter and then the max

Mon May 21 21:35:50 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * optimize assembly generation
  
  this little optimisation results in quite some speedup. e.g. solid 6 piece
  butt file went down to halve the time, others are even more interesting...

Mon May 21 21:20:06 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * implement iterative search function for assembler 1, the search is not interruptible but not savable

Sun May 20 17:59:11 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * simplyfy assembler 1 a tiny bit

Sun May 20 17:01:55 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * the new assembler now properly reports the end of the calculations

Sun May 20 17:01:05 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * change the solide 6-piece burr example so that is it finished when loaded

Sun May 20 16:47:58 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * implement the fast row removal for the assembler 1 matrix
  
  now the new assembler should be fast enough to be really quicker for
  all multi piece puzzles...

Sun May 20 16:30:36 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * another twiddle with the time and solutions in the solver tab

Sun May 20 11:18:01 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * groupseditor now properly edits min and max piecenumber for all shapes

Sun May 20 11:17:05 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix problem in piece list on problem tab, sometime groups were not shown

  * harmonize piece button labels, also correct the all+1 action, the min increase was missing

Sat May 19 19:25:44 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * shuffle elements in solver tab a bit around to make some more space

Sat May 19 18:24:14 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * add an option for the assembler to keep mirror solutions
  
  this will be useful later on, when having a proper solutions browser
  when all mirror solutions are removed it might be possible that the number
  of solutions for a certain piece set changes, when other pieces appear
  or disappear because there suddenly exists a mirror solution with the other
  pieces and the first solution is removed

Fri May 18 18:24:55 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * when unmirroring pieces we also have to take unplaced pieces into acount
  
  unplaced pieces then do become places, and the original mirrored piece unplaced
  this allows to find mirror solutions that are made out of other pieces from the
  set of available pieces

Fri May 18 18:22:42 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * reduce now returns the piece it is working on in assembler 1

Thu May 17 20:12:16 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * theoretically is is possible to cover single rows multiple times, so don't assume next row here

Thu May 17 20:11:32 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * hide rows in assembler 1, once they are processed

Thu May 17 15:54:33 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * more cleanup, remove unneeded checks

Thu May 17 15:30:02 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * cleanup in assembler 1
  
  factor out the row hiding into function now using only one vector for the hidden rows
  and not a stac variable. This will enable saving and loading further down. It also
  maked the recursive function smaller

Thu May 17 15:13:50 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * more cleanup in assembler 1

Thu May 17 14:38:57 CEST 2007  Andreas Röver <roever@users.sourceforge.net>

  * add an example for the piece ranges

Sun May 13 13:16:59 CEST 2007  Andreas Röver <roever@users.sourceforge.net>

Sun May 13 13:15:04 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix an infinite recursion problem in assembler_1

Sun May 13 13:11:04 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix piece list for problem: ranges and groups were not properly displayed together

Sat May 12 09:55:46 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * deactivate the assembly sections, they are way too hard to keep them working

Fri May 11 20:37:56 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * free memory for assembly when counting assemblies only

Tue May  8 11:35:51 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix mirror piece detection. This should fix the mirror removal problem

Tue May  8 11:26:38 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix uninitialized pointer in PieceVisibility widget

Tue May  8 11:25:54 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix another problem with the mirror code (see comment added in the code)

Mon May  7 20:02:46 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * empty assemblies are now created a different way, so remove that code

Mon May  7 17:50:38 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * make saving of non placements a bit more economic
  
  a non placement is now saved as a single "x" in the list

Mon May  7 17:50:07 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * proper min max check for assembler 1, to generate proper error messages

Mon May  7 17:49:32 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * remove unused parameter in assembler_1 prepare

Mon May  7 17:48:19 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * add a button to reset minimum to zero, also some more updates to interface for min-max

  * if a piece is not used in the solution the piece visibility list will not display its name
  
  this is intended to make it easier to see, wheter a piece is used in the acutally selected
  solution

Sun May  6 21:37:28 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * replace shape count by a range
  
  this will make it possible to search for solutions containing a piece or not. E.g. it
  is now possible to search the 6 piece burrs (for example all solid ones, ...)
  
  Editing is not yet properly supported in the GUI, right now it is just displayed

Sun May  6 18:27:59 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * make BurrTools handle unplaced pieces
  
  this has always been prepared but never used and so it never properly worked. A piece
  is placed if its transformation is not 0xFF. This is now properly wrapped and checked
  in all placed where necessary (at least I hope so). 
  
  The patch also increases the possible number of pieces from 255 to MAXINT. This limit
  was caused by using an unsigned char as index into the placement...

Sun Apr 22 12:24:40 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * calculation of getFinished is now better and doesn't jump around any more

Sat Apr 21 17:14:00 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * add the new dancing link assembler
  
  this assembler is __WAY__ faster then the old one if it comes to multipieces
  it is a bis slower when only single pieces are involved. That is why the old
  one will live on. The old assembler will be simplified to only handle single
  pieces once the new assembler is working properly.
  
  So what works: it can assemble.
  
  Placement browser is not working, the reduction is not yet up to paar with the
  old assembler (the fast line removal is missing)
  
  The assembler is seleced in a factory function in the gridType_c class. In case
  it is neccessary to remove it just remove the selection of the new
  assembler in this class and make the canHandle function of the old assembler
  return always true
  
  Right now there are also quite some commented out debug prints left. They will vanish
  over time...

Thu Apr  5 21:40:51 CEST 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix 2 problems in mirroring of assemblies
  
  - one problem was that non minimized pieces didn't work properly (they jumped around)
  - the other problem was that the wrong shape was calculated to do the hotspot and
    bounding box calculations with resulting in wrong new coordinates
  
  all this resulted in not properly working mirroring of assemblies and thus in not
  working mirror solution suppression (or only sometimes working)

Sat Mar 17 18:31:32 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * make mirror check initialisation handle identical pieces
  
  if there were 2 identical pieces in the problem (not multipieces but 2 identical ones)
  the initialisation of the mirror check structure went wrong. Now it works

Sat Mar 17 13:11:07 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * we may need to check for mirrors even when all rotations can be excluded
  
  the assembler didn't check for mirrored solutions when it tas shure that
  all possible rotations can be exluded. But mirrors are independend of
  rotations. So separate these 2 from one another

Sun Mar 11 17:33:01 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * properly set bounding box for empty shapes to all zero values
  
  this solves an assert, when problems contain empty shapes. THe bounding box was
  set too large and the compare in BB function tried to read the valued within
  that large BB and so tried to read invalid values

Sun Mar  4 13:21:16 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * a special begin method for the layouted window, to begin adding widgets to the window
  
  this is necessary because the layouted windows required you to add the widgets to the
  layouter inside the window, otherwise you will get problems. This of course only works
  when you have the right kind of pointer as the begin method is _NOT_ virtual

  is is solved by taking the transformation apart into 2 transformations and applying

  allowed values

Sat Mar  3 17:08:03 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * solve problem with transform point giving non integer results
  
  this is only possible with spheres and their crazy rotation problems...

Fri Mar  2 18:25:58 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add the part of FLU that burrgui uses to the source
  
  I did this because FLU is not really a widely used library and some big dirstros like debian or
  gentoo don't contain it. When this library is no longer required chances rise that BurrTools
  get included there, making installation for Unix users simpler, so let's cross fingers

  this took up a lot of time for shperes, the check now is simpler
  and only tests for the actual shape. It used to check for all possible

  transform calls each time the symmete calculation was called for the sphere
  it also saved quite some time for the other spaces, but only on startup

  * add checks for gridtype and variable voxels to the STL export

Sat Feb  3 20:46:17 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * some improvements to STL export
  
  -remove whitespace at the end of lines
  -make static variables static
  -make filename string in export function as long as the snprintf calls expect it to be
  -inform the user with message boxes about reasons, why the export failed
  -remove unneeded headers and the not required multiple inherited class
  -clean up the dialog widget positions and give them some meaningful minimum sizes for the expected content
  -the piece selector takes up the rest of the available space vertically

Sat Feb  3 20:44:05 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add a stretch function to layouter which maked the widgets stretch into the available space

Sat Feb  3 18:32:11 CET 2007  smiteo@yahoo.com
  * stl-export

Sat Feb  3 18:30:33 CET 2007  smiteo@yahoo.com
  * stl-export

Sat Feb  3 17:53:57 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * 17 new symmetry groups for triangle space

Sat Feb  3 16:56:37 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * introduce initHotspot function
  
  this function initializes the hotspot in a proper place
  sauitable for the gridspace so that the position of the
  hotspot stays valid through all possible orientations
  
  this is necessary for spheres as there it might happen that
  is turns out to be in a place that is not valid if the hotspot
  is always at 0;0;0, so with spheres we put the hotspot at
  a non empty voxel close to 0;0;0 all other spaces currently
  always use 0;0;0

Thu Feb  1 21:21:35 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add a column to the status window that shows whether the symmetries of all pieces are known

Thu Feb  1 21:09:29 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * 8 more symmetry groups for sphere space

Thu Feb  1 17:59:27 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add BallRoom and update other examples
  
  add comments everywhere, minimize where not done, add proper weight and resolve

Thu Feb  1 17:57:17 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * aftermath of the typo corrections, this is just reindenting of paragraphs

Thu Feb  1 17:56:20 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * simplify triangular minimisation and proper implementation for sphere minimisation

Thu Feb  1 17:17:37 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * the real headers have a capital letter H

Thu Feb  1 16:58:06 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * loots and loots of typo corrections for documentation

  * documentation updates

Wed Jan 31 17:26:34 CET 2007  Andreas Röver <roever@users.sourceforge.net>

  used to sed the window size, not it only does, when window invisible
  at that moment

Wed Jan 31 16:49:21 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix comment editing box problem with a too high label

Tue Jan 30 20:29:00 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * proper centering and move to origin for triangles and spheres

Mon Jan 29 21:49:02 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix color mark drawing in sphere grid editor

Mon Jan 29 19:19:18 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * mention Markus in AUTHORS for his hints with the spheres

Sun Jan 28 21:49:27 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * rotation matrices are static for module...

Sun Jan 28 21:48:18 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * use rotation matrixes for triangle space generator and point transformation, more will follow

Sun Jan 28 21:44:15 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * don't rotate a shape for bounding box calculation if not necessary
  
  this saves us cycles as this function is quite often called with 0 as
  transformation and the transformation sometimes changes things (e.g. in sphere
  space where after a transformation the space can get smaller...)
  This resulted in skips in rotated assemblies -> not proper rotated assembly reduction

Sun Jan 28 21:42:46 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix another skipping transformed assembly problem with triangle space
  
  the problem was that the (0,0,0) vector can not be rotated onto
  itself because of parity changes in the target triangle, so we have to
  consider this small shifts

Sun Jan 28 14:06:46 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * also include mirror matrices in sphere space 
  
  this allows us to remove the mirrorX function

Sun Jan 28 13:41:08 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * use rotation matrices in space grid 0 as well
  
  they are more flexible, the do now include the mirroring, so
  all transformations can be done in one step, which is way cheaper
  than the up to 4 copyings required to generate a transformation
  before (mirrorX, rot along all 3 axes...)
  
  It also removes quite a bit of code as the rotation functions have
  been quite big.
  
  Triangles will be switched over next

Sat Jan 27 20:57:34 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * virtualize scale functions and fix scaling for triangles

Sat Jan 27 20:00:56 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix centering of objects in sphere space

Sat Jan 27 18:10:13 CET 2007  Andreas Röver <roever@users.sourceforge.net>

  * invalidate symmetry after rotating aroung z in triangle space

Sat Jan 27 17:39:42 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * remove all unneeded rotate and mirror functions, the ones left are private now

Sat Jan 27 17:19:51 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * now all grid spaces use no rotate and mirror functions any more in the gui

Sat Jan 27 16:59:22 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * proper rotations and flips for triangle space, also only using transform

Sat Jan 27 16:39:09 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * proper rotations and flips for sphere grid using only transform
  
  we will do that same for all grid spaces: only use transform, when we
  can remove the rotate and mirror functions from voxel space where
  they don't really belong as not all spaces can be rotated one way or
  another

Sat Jan 27 16:19:21 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * proper nudging for the new space grids

Sat Jan 27 16:18:35 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * it makes no sense to "scale" sphere grid space, so remove those buttons

Sat Jan 27 14:42:07 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * voxel actionOnSpace function now uses the getNeighbor function to find neighbors
  
  this used to be fixed coded and only worked for brick space, now also speres are
  working properly and it is possible to make inside spheres variable...

Sat Jan 27 13:47:31 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * initialize symmetries after loading voxel space

Sat Jan 27 13:47:12 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * missed one include file

Sat Jan 27 13:27:55 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * gzstream include must be local

Sat Jan 27 13:26:17 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * overhaul of build system, now the generated files in tabs_x are created automatically

Sat Jan 27 10:35:37 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add some symmetry search functions for spheres

Fri Jan 26 22:08:47 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * make the triangle space generator independent from libburr, now we can include them in the makefile

Fri Jan 26 21:56:43 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * make generator for brick space independent from burrlib

Fri Jan 26 21:30:39 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * make generator for space grid 2 independent of library

Fri Jan 26 21:29:25 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * bitfield uses asserts

Mon Jan 22 19:09:10 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * Add Bill Cutlers Bermuda puzzle

Sun Jan 21 16:55:37 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * factor out size buttons of tool tabs

Sun Jan 21 16:34:46 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * factor out the code to resize a space in the tool tab

Sun Jan 21 16:26:42 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * factor out the tool button tab

Sun Jan 21 16:09:05 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * move 2 wigets only used by tool tab to tool tab file

Sun Jan 21 15:47:03 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * the tabs with the edit tools can now be different for all grid spaces
  
  right now they are 3 cpies of one and the same class, except for the small
  text difference to see, which grid space is active. Later on we will implement
  different tools for all the grid spaces or have different activities for
  different spaces (e.g. nudge only by 2 units, ...)

Sun Jan 21 13:25:44 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * huge speedup for layouter
  
  first when a layouter widget was resized it used to call the Fl_Group resize function, which first
  placed all widgets resulting in recursive layouter call for all those placements and then the 
  layouter placed the widgets again resulting in another recursive cascade. That is removed now by
  only calling the Fl_Widget resize
  
  second the minimum size of a layouter stays constant normally, so cache that value for later calls
  to the function.

Sun Jan 21 09:35:54 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix bug when calculating minimal tab size
  
  the width and height were not properly initialized resulting
  in huge sizes from time to time, now a minimal size of 10 is assumed

Sat Jan 20 17:34:25 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * simplify hotspot calculation in sphere space
  
  as the hotspot calculation might be done after the loops anyway
  we don't need to have that check inside the loop

Sat Jan 20 15:20:53 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix assembly rotation for sphere space grid
  
  2 things were wrong:
  - if the hotspot was on an empty voxel is was not updated when rotation
  - the transformation multiplication matrix was calculated wrongly, the mirror matrix was applied wrong

Fri Jan 19 21:51:23 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * copy and paste, bitfield print function doesn't need to maintain the index

Fri Jan 19 17:39:27 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * convert bitfield to use proper linebreaks (UNIX) and start using standard int types with lengths

Wed Jan 17 21:34:04 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix bug in loader for assemblies that made negative number below -9 load wrong

  * add another missing file (bitfield)

Sun Jan 14 19:11:30 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add the assembler frontend for the sphere grid space

Sun Jan 14 17:38:40 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * proper deinitialisation of PieceVisibility viewer, valgrind complained

Sun Jan 14 17:35:01 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * simplyfy toggle 3D and grid editor function a bit, the layouter makes it possible

Sun Jan 14 17:30:12 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix layouting problem after toggling the 3D and the grid editor

Fri Jan 12 22:21:01 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * validate coordinates before editing them in grid editor
  
  this is necessary for sphere as they do have voxels that do not belong to
  the space but thay would be edited by the grid editor and would break havoc
  that way
  so a new virtual validate function is created with default implementation always
  valid and a specialisation for spheres.
  at the same time the recoursive set function is made a part of the class to have
  better access to class memebrs and now requires less parameters

Fri Jan 12 21:58:02 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * another 11 sphere symmetry groups

Fri Jan 12 21:23:14 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * search for all sphere symmetry groups of 3x3x3 spaces and add them

Thu Jan 11 21:15:30 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix spheres generator, the matrix multiplication was not stored correctly

Thu Jan 11 20:49:56 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * handle mirrors in sphere transformPoint

Thu Jan 11 20:49:20 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * 3 more symmetry groups for spheres

Thu Jan 11 18:16:56 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * fix transformPoint for triangles, this has been wrong a loooong time

Tue Jan  9 19:17:00 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * proper implementation for symmetry calculation tree in generator for space 2

Tue Jan  9 19:01:00 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * some more symmetry groups for spheres

Tue Jan  9 18:03:17 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * update generator for grid space 2 (spheres) now transformed assemblies are suppressed

Tue Jan  9 14:43:10 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add symmetries and assembler frontend for spheres

Tue Jan  9 14:42:20 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * proper hotpot update for transformation and correction to transform point in voxel_2

Tue Jan  9 14:40:50 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * nobody uses the symmetry mask directly, so remove that function and properly virtualize the only user

Tue Jan  9 14:39:30 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * proper positioning of spheres in the voxel drawer

Tue Jan  9 14:38:47 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * due to the large symmetry vectors of spheres, we need a lerget buffer here

Sun Jan  7 11:47:02 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * proper neighbors for spheres

Sun Jan  7 11:46:17 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add some pointers to one message, this message confuses people, so tell them where to read

Sun Jan  7 11:44:29 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * implement transformation for spheres, also toggle logic, (0;0;0) is a valid coordinate

Sat Jan  6 17:15:33 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add the missing files for the new space grid to darcs repository

Fri Jan  5 21:16:50 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * virtualize transform
  
  the transform function is really the work horse when it comes to generating alls
  possible orientations. It it the only function used for that by the libraray. the rotxyz
  functions are only used by the gui. So make transform virtual so that each class can
  have its own implementations as spheres nees another aproach and can not work with
  the current scheme of adding up several rotxyz calls. This also removes the rotxyz members
  from sym, as nobody needs them the rot arrays are now part of the voxel_x_c classes
  
  later on rotxyz will be removed from the voxel_c class as they are really dependend
  on the grid space if they do make a sense at all

Fri Jan  5 20:42:29 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * transformations can fail in sphere grid space, so we can not use it in constructor
  
  this patch removes the transform parameter from the voxel space constructors and
  places the transform call after that and either adds asserts or checks to in
  the right places to check for the result of the transformation

Thu Jan  4 21:21:34 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * remove parameters for the cube space they were no good aproach
  
  I need to think about this again but this is no good because the user
  - can not exactly define the shape to use and opten the resulting shape looked wrong
  - too complicated logic for the programming

Thu Jan  4 21:06:39 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add voxel_2 class, right now it is just a copy of voxel_0 plus the rotation matrixes

Thu Jan  4 21:06:14 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * NEWS, clarify disassembler

Wed Jan  3 20:39:57 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add spheres as a new possible space grid
  
  currently the grid editor and the voxeldrawer do work ok but still need improvement
  the variable voxel markers are missing
  no dedicated voxel space -> no proper transformations, no symmetry checks, ....

Wed Jan  3 20:39:35 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * typo in makefile generator in a filename

Tue Jan  2 18:24:21 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * add buttons to add one instance of all shapes and another one to remove all shapes

Tue Jan  2 18:23:20 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * better toggling of 3D area and grid editor
  
  it is still not perfect with the new layouter, but working at least again most of the time

Tue Jan  2 18:21:25 CET 2007  Andreas Röver <roever@users.sourceforge.net>
  * proper minimum size for grid edit group

Sun Dec 31 19:07:01 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * make the rest of mainwindow use the layouter so now it is completely layouted

Sat Dec 23 21:11:17 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * update NEWS file with a few more things

Sat Dec 23 21:09:04 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * update stale comment

Fri Dec 22 14:45:01 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * enable and disable the new buttons on the solver tab when the puzzle is currently solved

Fri Dec 22 10:11:40 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * add a coment for the hash node reference count

Thu Dec 21 11:23:05 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * move the reference count increasing for the disassembly nodes to the proper place

Thu Dec 21 11:17:41 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * simplyfy disassembler find state loop a bit

Wed Dec 20 19:59:30 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * get rid of the deletelist in disassembler, use the reference counter of the nodes instead

Wed Dec 20 19:36:43 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * newNode always returns a valid value, so no need to check that

Wed Dec 20 19:36:12 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * some comments

Wed Dec 20 19:33:51 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * use a hashtable in the disassembler for node merging
  
  this used to be a list but the list can get up to 60 entries large and then
  checking all entries if they are equal to a new node can be expensive

Wed Dec 20 19:33:29 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * some const correctnes

Wed Dec 20 19:32:50 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * cache the hashvalue for disassembler nodes

Sat Dec 16 18:15:07 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * add some coments to the checkmovement function in disassembler

Sat Dec 16 18:06:09 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * add missing include

Sat Dec 16 17:58:40 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * save direction and amount of movement with the disassembler nodes
  
  with this information the node merging can be done much faster because
  we don't need to find this information, also the newnode function was simplified
  because of some interface changes

Sat Dec 16 16:40:10 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * improve prepare2 function of disassembler
  
  not we only do another loop if it is really necessary, the check costs extra time
  but is doen't raise the level of the function. The function is still O(n^3) but
  we can save one of the n^3 loops

Thu Dec  7 18:10:54 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * more tweaks to node hashtable in disassembler
  
  - nodes are now a real hashnode instead of stored in a struct that is a hashnode. This
    saves us loooots of new and delete calls
  - hashtable starts smaller and grows faster

Wed Dec  6 21:11:57 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * optimisation for node finding
  
  when finding nodes don't save doubles. This should help improve performance
  because merging needs to be done with less nodes

Wed Dec  6 21:07:07 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * optimisations for newNodeMerge
  
  bail out as fast as possible, if we can not return a valid node
  so if the movement of pieces differ -> return

Wed Dec  6 21:05:40 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * optimisations for the check movement function
  
  one check is moved up so that the inner part can be avoided earlier

Wed Dec  6 21:04:23 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * improvements to node hash
  
  - the node hash can not grow
  - some optimisations for fatser initialisation and deletion
  - start with smaller hash table for less memory consumption

Wed Dec  6 21:02:27 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * change hash function for node hash so that is if faster to calculate

Tue Dec  5 18:25:51 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * Checkmovement returns now only equal movement
  
  Checkmovement used to return different amounts of movement for different pieces
  that disturbed quite some other parts, now all pieces are wither stationary or
  move by the amount given to that function
  
  That also makes the check for even movement in the new node function unnecessary
  and so it could be moved over to the mergenode function

Tue Dec  5 18:24:50 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * burrTxt can now only redisassemble the already found assemblies in a file

Sun Nov 26 14:45:45 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * disassembler uses the max weight instead of the sum of the weights

Sun Nov 26 14:31:45 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * Fix crash on toggling piece visibility when no solution is displayed
  
  When you toggled a visibility and for example the problem display ways visible in the
  3D window the program could crash because it tried to check the visibility for more
  3D shapes than there were blocks in the selector

Mon Nov  6 21:07:43 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * use proper font for gui elements in documentation

Mon Nov  6 21:06:23 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * new images for documentation with new gui elements

Sat Nov  4 18:29:02 CET 2006  Andreas Röver <roever@users.sourceforge.net>

  * update documentation with space grid, weight and the new buttons on sovler tab

Tue Oct 31 13:13:57 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * doxygen commenting

Fri Oct 27 20:07:10 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * remove the window frame from the images inside the documentation

Thu Oct  5 18:55:01 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add a doxygen configuration file

Sun Sep 24 15:11:25 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * increase readability of code in the disassembler a bit

Sun Sep 24 15:09:58 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * use a hashtable in the disassembler to store closed nodes
  
  this should hopefully increase speed as the looup operation of a hashtable
  is way faster than the one in a binary tree as was used for the old set

Sun Sep 24 15:00:17 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add a section with hints and tips for emulation other space grids. Right now only headers

Sun Sep 24 14:59:41 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add Ronald as author to the documentation

Sun Sep 24 14:51:04 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * properly reset groups after searching, this silences a warning

Sun Sep 24 14:49:39 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * proper padding for button groups to make them look like in the old version before going to layouter

Sun Sep 24 14:48:46 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix unused variable varning inside thr tr module

Sun Sep 24 14:47:29 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add possibility for buttons to specify padding between label and button frame

Sun Sep 24 14:46:03 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add virtual destructors for all classes that miss them

Sun Sep 24 11:58:49 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * gcc doesn't accept class::member inside the class declaration
  
  make compilabe with gcc 4.1.1

  * small optimisation in disassembler_0

Tue Jun 20 18:25:58 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * assert to make shure we don't free more than once

Tue Jun 20 18:22:37 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * new disassm to moves option for better image generation
  
  now the active part, where things are moving is always in the
  center and not like in the old one where, when the removed
  part required further shifting, the action took place somewhere else

Tue Jun 20 18:20:38 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * proper local lables for the i86-asm part of the dancing link assembler, now it works again

Sun Jun 18 11:58:46 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * better disassembly breadth first search
  
  this search does keep only the nodes that are really required
  and drops nodes that are useless. This speeds up the process as
  less nodes need to be searched when a new node is included in
  the list it also saves memory as less nodes need to be saved
  
  The patch also fixes a problem with the old node merging algorithm
  which was wrong because of the weights and which also merges wrong
  nodes together

Fri Jun 16 16:23:26 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix crash for constrains buttons

Fri Jun 16 16:08:06 CEST 2006  Andreas Röver <roever@users.sourceforge.net>

  all that we need now is to write our own tile class that
  doesn't allow the dragging of widgets below their minimal size

  * convert entity tab colors section

Mon May  1 12:38:12 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * replace hand placed widgets in the entities tab shape section with layouter
  
  this is just a first step. All other sections will follow, followed by
  a replacement of the tile group to make shure you can not
  drag widgets smaller than their minimum size. This will not be
  possible with the standard tile widget

Mon May  1 11:01:57 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * remove unused constructors from flat button class

Mon May  1 10:44:17 CEST 2006  Andreas Röver <roever@users.sourceforge.net>

  * move includes in MainWindow from header to cpp file, this saves compile time for main

Mon May  1 09:33:44 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * clean up image export file and class name

Mon May  1 09:05:28 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * this include is no longer required

Mon May  1 08:50:10 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * rename configuration class to configuration_c

Mon May  1 08:45:36 CEST 2006  Andreas Röver <roever@users.sourceforge.net>

  * sort files in makefile alphabetically, well more or less

Sun Apr 30 21:32:40 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * image file and class names cleanup

Sun Apr 30 21:24:18 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * cleanup of disasmtomoves classes, moved them also into lib as they are not really gui

Sun Apr 30 21:07:46 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * rename pieceColor to piececolor

Sun Apr 30 21:01:15 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * ArcBall_c -> arcBall_c proper name for that class

Sun Apr 30 20:49:46 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * rename acrball file to all lowercase
  
  more files are going to follow. This is the start of a cleanup to
  get some kind of rules into filenames, and typenames

Sun Apr 30 17:02:42 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * merge VoxelView into voxelDrawer_c
  
  This needs some more cleanup, but there was no reason for the
  VoxelView base class any more

Sun Apr 30 17:02:08 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix static linking against flu and fltk

Sat Apr 29 13:58:31 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * set value of solution selector properly when activating first found solution

Sat Apr 29 13:51:32 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * select proper solution after deleting some of them

Sat Apr 29 13:44:28 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * properly place solution selector on Solver tab

Sat Apr 29 13:29:56 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * implement dropping of disassemblies and only keeping the disassembly information so save memory

Sat Apr 29 09:52:40 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * more updates to NEWS file

Fri Apr 28 22:10:59 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * simplify the already implemented sorting with new disassembly info class and implement missing
  
  we now only use the disassembly info for comparison. This class is always
  creates, even when the complete disassembly is available. Comparisons
  are faster with is anyway so it should be worth it

Fri Apr 28 20:27:25 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * update 2 puzzles with new weight feature

Fri Apr 28 16:37:37 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * update news file with new developments

Fri Apr 28 16:32:36 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * implement weights in the disassembler
  
  when the disassembler has found a new move it adds the weights
  off all pieces that move and all pieces that stay and if the
  weigth of the steady group is larger, this group is moved instead
  in the opposite direction

Fri Apr 28 16:31:52 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * solution number and assembly number should not be displayed in scientific form

Fri Apr 28 16:30:55 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add gui for the weight field

Fri Apr 28 16:28:33 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add a field "weight" to voxel spaces
  
  this field will allow the disassembler to properly select which
  pieces to move. So it is possible to keep frames and boxes steady
  while the inner pieces move around

Fri Apr 28 16:27:09 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * replace internal structure of separation info class with something simpler
  
  this new version requires less memory it is a prefix order
  array representation of the tree, now we can save and load properly

Fri Apr 28 16:25:35 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * update news

Thu Apr 27 21:58:29 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * proper sort, even for solution info only cases

Thu Apr 27 16:51:52 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * when loading a disassembly info, check, if there actually is one

Thu Apr 27 16:44:19 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * show a window when recalculating all disassemblies

Thu Apr 27 16:38:14 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix for function that removes information from movement cache for one piece
  
  the entry counter was not decreased, even when elements were removed

Thu Apr 27 16:37:27 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add possibility to display some information about the usage of the movement cache

Thu Apr 27 16:36:50 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add buttons to replace disassemblies by disassembly info and recalc disassembly and other things with disasms

Thu Apr 27 16:33:47 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix for loading in assembler 0. The last entry may be not complete
  
  the last entry will only contains valid information for the
  status array, all other fields are too small anyway, so skip them
  for the last (meaning the one that is equal to piecenumber)

Wed Apr 26 22:03:11 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * show disassembly information, if present

Wed Apr 26 22:01:19 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add function to delete solutions without disassembly (info)

Wed Apr 26 21:55:58 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add separation info to puzzle and solution classes
  
  now you can have a treeInfo field, if the tree field is empty

Wed Apr 26 21:54:24 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add a separation info class that contains part of the information of the disassembly class
  
  this part is the dificulty of the disassembly, the number
  of moves and the level information. This class will be used
  to have a more memory efficient way of saving the important
  information of a solution fr huge puzzles with lots of assemblies
  and many solutions

Tue Apr 25 20:31:51 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * implement proper removal of mirrored solutions from the list of found assemblies
  
  we have to try to exchange pieces that are mirrors of one another
  after doing the mirror transformation, to try to remove mirror
  orientations from the assembly
  
  The mirror pairs are detected in the prepare function and given
  to the assembly transform function via parameter

Tue Apr 25 20:00:31 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * initialize the edit choice once after startup

Tue Apr 25 19:24:37 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * initialize variable to make valgrind happy

Sun Apr 23 11:51:37 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * remove some unused code from assembly transformation

Sat Apr 22 22:44:00 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix in rotation check
  
  this fixes a problem, that occures, when the pivot piece contains
  mirror symmetries. Then the comparison works even, if there are
  mirrored shapes inside the transformed assemblies. Of course mirrored
  shapes are not available and so the assembly is invalid
  
  There is, of course the possibility to swap to pieces that are the
  mirror of one another. This needs to be inserted, but I will not
  do that right here

Thu Apr 20 17:57:15 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * the hotspot is in the center of the voxel given by its coordinates
  
  this simplifies the code because the hotspot doesn't change place
  when doing a rotation, as it was necessary for triagonal prisms
  
  It also allows toload the old savegames as they were calculated with this
  assumption and the had been changed a while ago

Thu Apr 20 17:56:26 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * print some more information when showing a voxel space

Thu Apr 20 17:55:38 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * remove debug code, no longer required I assume the code is working

Wed Apr 19 16:42:54 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * implement solution sorting and deletion of solutions

Tue Apr 18 18:10:30 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * remove no longer needed parameter from checkmovement function

Tue Apr 18 18:06:43 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * proper solution for the multi-piece movement checks, also add some consts, where suitable
  
  this solution is also much faster. It creates all merges with all
  already found movement nodes with each new found node instead
  if checking the movement possibility for groups of 2 pieces

Mon Apr 17 19:03:49 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix warnings

Mon Apr 17 19:02:12 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * replace fl_ask with fl_choice, as the first one is going to be removed and results in warnings

Sun Apr 16 20:47:04 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * z size doesn't change in rot z

Sun Apr 16 20:46:05 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix warnings

Sun Apr 16 20:45:52 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix warning

Sun Apr 16 20:35:08 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * don't use that strange deallocate template any longer, the for loop is simpler to understand

Sun Apr 16 20:33:43 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * if drop solutions, we must free them

Sun Apr 16 20:33:03 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * we need to free the voxel spaces in the voxelviewer, when the viewer gets deleted

Sun Apr 16 20:32:44 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * free gui grid map, when main window closes

Sun Apr 16 20:32:01 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * now the prixmapList also for the images directly in the main window

Sun Apr 16 19:00:49 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * widgets don't free assignes images, so we need to do that
  
  this is handled by a new class that has a list of all allocated
  images. The class is used for the tool tab images, others are still
  missing

Sun Apr 16 19:00:24 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add destructor for pieceVisibility list to free allocated memory

Sun Apr 16 11:20:34 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * move the changelog creation at the start of the bootstrap script, as the other commands need it later on

Sat Apr 15 18:41:25 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * when the list gets full for unsorted entries, we now keep only every 2^n-th entry

Sat Apr 15 16:34:20 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * save the assembly and solution number with each solution

Sat Apr 15 10:05:18 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * multi-pieces must not be symmetry breaker, it may break the assembler

Fri Apr 14 22:36:54 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add possibility to limit the number of solutions saved
  
  this doesn't work right now for assembly only solutions
  as it can only make a choice for solutions with disassembly
  by dropping the less interessant solutions

Fri Apr 14 14:10:01 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * add gui for sort method functionality in last patch

Fri Apr 14 12:19:06 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * assembler thread can now sort n different ways, implemented level sort
  
  level sort sorts so that the highest level is at the top
  if the first level is equal the 2nd level is used for comparing

Fri Apr 14 11:06:48 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * move the sorting of solutions out of puzzle, into assemberThread
  
  this is the 1st step in making a more powerful solution saving
  engine with more choice for the user, like different sorting
  saving only parts of the solutions, ...

Thu Apr 13 21:49:01 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * lower changes for the occurance of a fatal problem with the assembler
  
  the problem occures when a multi-piece is selected as symmetry breaker
  and later on a voxel is selected that can not be filled with the 1st
  of the multi-piece and thus the 2nd gets selected.
  
  The "solution" right now is to try to not choose a multi-piece as symmetry
  breaker even if the symmetry conditions are better.
  
  Now the problem can only occure in problems that have only multi pieces

Thu Apr 13 21:21:40 CEST 2006  Andreas Röver <roever@users.sourceforge.net>

Sat Apr  8 15:20:29 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * make status window really usable
  
  the status window now includes connectivity information
  for the shapes, meaning is the complete shape conneced
  with faces, edges or only corners
  and does the shape contain a hole in 2D (z-direction is
  not considered) and 3D

Sat Apr  8 10:40:45 CEST 2006  Andreas Röver <roever@users.sourceforge.net>
  * move the prepare functionality into the assembler mking the frontend classes much slower with this
  
  the prepare function can still be overwritten, if necessary, but for
  the current 2 space grid only the piece fits function differ by one line, so
  this saves us about 5kByte code

Fri Apr  7 21:50:21 CEST 2006  Andreas Röver <roever@users.sourceforge.net>

  * remove generated code from symmetriy class files into inc files
  
  We now have as source only the possible rotations and the symmetries
  All other tables are calculated and written into include files that
  are used by the symmetry classes. This generation is done by the
  generator program, as this needs a working library bootstrapping
  is a bit complicated
  
  this patch also removes the class definition of symmetry_0 in the
  symmetry header file

Fri Mar 24 22:11:47 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix "Piece x can be placed nowhere within the result"
  
  the preparator didn't return the shape id, but the index

  behaviour when the pieces were not sorted

Fri Mar 24 21:58:29 CET 2006  Andreas Röver <roever@users.sourceforge.net>

  * add the GPL file header

Thu Mar 23 18:10:27 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * rename SquareEditor to gridEditor_0_c
  
  this also lead to some cleanup within the usage of the enums
  and also the functions in the guigrittype factory are const

Thu Mar 23 17:46:56 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * introduce gridEditor_c as base type for SquareEditor
  
  this is highly probable not the right final solution but a start

Thu Mar 23 17:03:54 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * introduce guigridtype class
  
  this class is the factory for the grid type dependent widgets
  just like gridtype class is the factory for the parts of the library

Thu Mar 23 17:01:47 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * get rid of the label in the voxel drawer and voxel view widgets

Mon Mar 20 20:46:35 CET 2006  Andreas Röver <roever@users.sourceforge.net>

  * bitrot on tester, lets for now comment out most of it, we will care for the useful functions later on

Mon Mar 20 20:25:24 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * voxel_c is not the base class for all voxel classes, voxel_0_c as usual the subclass for bricks
  
  for now only the rotate functions are virtual, but more are surely to come

Mon Mar 20 17:18:49 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * move the missing 2 voxel constructors to factory creation
  
  This patch temprarily disables the currently unused the piecegenerator

Mon Mar 20 17:18:08 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * missed copying the symmetry class then copying assemblies

Mon Mar 20 16:46:59 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * some optimisations in tester and add functions to analyze parallel epipedions in tester

Mon Mar 20 16:43:41 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * also update the result id, when a shape is removed from a problem
  
  this fixes a crash, when opening the puzzle tab, because of an
  invalid result shape id. The id was for the last shape, one shape
  was deleted, the result not updated, and became invalid

Sun Mar 19 21:49:04 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * comment out the possible future gridTypes, they only create warnings

Sun Mar 19 21:36:32 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * remove constness from gridType in puzzle
  
  this is required because the parameters of the gridType
  are in fact editable, you can just not change the type
  itself

Sun Mar 19 21:29:30 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * move symmetry creation to gridType factory

Sun Mar 19 21:16:13 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * move assembler and disassembler into gridType factory

Sun Mar 19 20:51:27 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * move voxel creation to gridType factory

Sun Mar 19 18:24:36 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * introduce gridType_c and make symmetries to a class
  
  This will finally lead to grid type independent code
  right now it replaces the define NUM_SYMMETRIES by the
  value sreturned by grid type and on that way introduces
  the class wherever necessary

Sun Mar 19 15:54:52 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * check result shape id after loading and reset, when invalid

Sun Mar 19 11:46:21 CET 2006  Andreas Röver <roever@users.sourceforge.net>

Sat Mar 18 16:40:25 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * remove a warning

Sat Mar 18 13:48:31 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * another update to symmetry calculation and avoidance
  
  The last update solving the squarrel bug resulted in a huge slowdown
  of JayCube because another piece was choosen for the symmetry
  breaker. This update results in JayCube using again the right
  piece for symmetry breaker. It passes the regression tests, so
  let's hope it's right

Sat Mar 18 10:54:29 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix bug with multi pieces that prevented finding solutions sometimes
  
  This bug occured in the multiPieceWhy puzzle file in the regression
  tests. THe problem was that the program expects to have at least
  n possible placements for a piece that occures n times, otherwise
  it is not possible to place them all. But the special first piece
  might have only one placement removing that from all the others
  and thus all other pieces might have only n-1 placement and that is
  still valid ad the last placement is in the first piece

Sat Mar 18 10:54:12 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * rename tabs in GUI

Sat Mar 18 10:52:59 CET 2006  Andreas Röver <roever@users.sourceforge.net>

  * reorder some mnemonics to achieve better memory access parallelity

Fri Mar 17 17:13:11 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * remove the 2nd updown entry from the assembler list of inputs

Fri Mar 17 17:06:20 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * merge the up and down array into one
  
  This frees one register for the assembler versions of the
  cover and uncover routines for intel cpus and this one
  free register allows for a much cleaner implementation without
  using stack and with 2 nearly identical implementations for both
  routines

Thu Mar 16 21:51:45 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * first version of an assembler implementation

  * update year for copyright in about box

Tue Mar 14 16:59:36 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix deadlock when pressing stop after the thread has already been finshed
  
  This is not completely save, but should work in most circumstances
  (it might fail when the thread stops between the start of the routine
  and the setting of the state)
  
  Also unpress the button

Tue Mar 14 16:36:07 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * rearrange the elements in the size changing tab a bit

Sun Mar 12 18:57:03 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * add separators for the other drag points in the problem tab

Sun Mar 12 18:45:00 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * take focus shortly when clicking into grid editor, this makes shure values are taken over from input lines

Sun Mar 12 18:30:40 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * do update the pieve visibility selector then the number of pieces changed
  
  this bug was introduces when not updating the selector when you
  just select another solution to not reset the state. But now it
  was possible to add new pieces to the selector and it didn't update
  this is fixed now

Sun Mar 12 18:14:21 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * make solution selector start from 1 instead of 0
  
  also check, if the current value of the slider is not
  bigger than the number of solutions (can happen when switching
  problems)

Sat Mar 11 17:24:03 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * fix for Browse placement button not enabled after a puzzle has been completely analyzed

Sat Mar 11 17:23:42 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * add the latest speedups to NEWS file

Sat Mar 11 17:07:29 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * cleanup and comments here and there

Sat Mar 11 14:42:48 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * add a placement removal phase before the reduction that is a more general form if the recently added speedup
  
  Its something like this:
  for a column c1: if there is a column c2 that has a 1 in each row c1 has a one then you can remove
  all rows that have a one in c2 but not in c1 because it is required for c1 and c2 to be one at the same time.
  
  this thinns out the matrix before the more expensive piece placement phase comes

Sat Mar 11 13:13:01 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * speedup for reduction
  
  the idea here is that if one piece occupies certain unit in all
  its placements it is impossible that any other piece can
  occupy that unit, so all placements for any other piece that
  uses that voxel can be removed. This lets the matrix shink
  must faster and saves us some of the costly cover and uncover
  operations. The results can be quite enormous: One of frans
  polycube puzzle where you put the pieces onto sticks went down
  from 377 to 27 seconds.

Sat Mar 11 13:11:06 CET 2006  Andreas Röver <roever@users.sourceforge.net>

  * some cleanup and useless code removal in reduce

Fri Mar 10 21:55:31 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * add clumps concept to speed up assembling of some puzzles
  
  This is taken from Bill Cuttlers program. In my implementation
  it means that we remove columns that are identical within the matrix
  as they don't contribute any information

Wed Mar  8 17:48:51 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * some more updates to the NEWS file

  * plut memory leak

Sat Mar  4 17:12:27 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * restructuring of image export
  
  image export is now done inside the callbacks of a voxelView class
  this is necessary because otherwise (e.g in the thread) the openGL
  context might be absent, this will also enable us to support later
  new voxel space types without a lot of work

Sat Mar  4 17:10:56 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * divide the image grabbing into 2 parts
  
  so that we can put these into the VoxelView callbacks
  also get rid of the OpenGL setup, as it's now done in the
  voxelView and we don't need that any longer

Sat Mar  4 17:06:31 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * restructuring of voxel output classes
  
  now voxel view is the base and responsible for rotation, scaling
  ligtning, ...
  
  voxelDrawer is only responsible for drawing cube based voxel spaces
  
  also add a callback class to VoxelView to make is possible to
  call functions pre and post the drawing of the voxel space

Wed Feb 22 21:40:48 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * Rework image export into state mashine Part III
  
  now the image output is done in small steps that only draw
  one image ino the OpenGL context and then return.
  What is left is to integrate this into the VoxelDrawer

Wed Feb 22 19:51:08 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * Rework image export into state mashine Part II

Wed Feb 22 18:47:04 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * Rework image export into state mashine Part I
  
  The image export can not be done in a thread, bu we need to do it
  in the draw function, but for that not to freeze the application
  we need to be able to do everything in small steps, this
  is the first part of this work

Wed Feb 22 18:20:26 CET 2006  Andreas Röver <roever@users.sourceforge.net>

  * correct comment

Mon Jan  9 10:29:23 CET 2006  Andreas Röver <roever@users.sourceforge.net>
  * improved the disassembler a bit
  
  the disassembler now no longer finds moves where one piece is moved
  x units and another piece is moved y units in the same direction
  
  the disassembler now finds moved where 2 pieces are moved in the same
  direction, until now it only found these when movement of the first
  piece forced the 2nd to move.
  
  This needs to be improved to larger groups of pieces.

  * new asserts that throw an exception instead
  
  this new scheme allows to catch after the lib produces
  an unsolvabale error. A window with some information is
  displayed and the program doesn't crash
  
  Sadly FLTK is by default compiled without exception support
  (what a crap) so the exceptions don't go through the callbacks
  and so the program still crashed on asserts in the GUI
  instead of saving the puzzle and shutting down

Sat Oct  8 14:51:09 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * add hotspot functionality
  
  a Hotspot is a point inside a voxel space that always stays at the
  same position reltvie to the shape defined inside the voxel space,
  so if you have the hotspot at some special corner and now flip rotate
  and shift the piece around inside the voxelspace the hotspot will stay
  at the same corner of the piece and move along with this corner
  
  What is that useful for?
  
  To rotate assemblies. because now it is possible to recalculate the
  orientation of a piece and calculate the new position of the hotspot
  independent of the concrete shape of the piece

  we really do need to return 0 when we do not handle the
  event or else key shorcuts will not arrive

Sat Sep  3 11:34:49 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * remove assemblyVoxel_c class
  
  we don't really need this class any longer. Assenblies are
  saved in the assembly_c class that saves the position of
  the pieces. This class was only kept because I've been too
  laze to rewrite the print routines thats done now

Wed Aug 31 21:15:58 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * fix for wrong handling of grouping class + optimisation
  
  we can sadly not assert that the user will not call the
  grouping class after it has returned false, so make sure that
  we do noting but return false once that happened
  
  als we don't need to evaluate the 2nd part of the puzzle once
  the first part turned out to be not disassembable

Wed Aug 31 20:41:46 CEST 2005  Andreas Röver <roever@users.sourceforge.net>

  * add configuration support
  
  for the moment a simple configuration, just 2 switches
  tooltips and the lightning in 3D mode. The configuration
  class also lacks the other data types except for bool, also
  the dialog needs some brush up, but it works for now...

Sun Aug 28 11:48:29 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * add better grouping of pieces for disassembler
  
  now each (set of) piece(s) can belong to several groups and
  the disassembler will assign groups as it progresses with
  its task. As soon as it hits a not disassembable set of
  pieces it looks if they can be assigned groups so that they
  are all in the same group

Wed Aug 24 16:48:22 CEST 2005  Andreas Röver <roever@users.sourceforge.net>

  * remove some unused functions from disassembly node

Thu Aug 18 16:30:06 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * handle more than one piece at the leafs of the disassm trees
  
  with the new group feature the ends of the disassm trees can
  now contain more than one piece, so we need to use a loop
  at the tree end and place all the pieces

Thu Aug 18 16:28:06 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * remove unused variable assembly from object disaasmtomoves

  * create a placement class that represents the position of a piece

Sun Aug 14 09:52:21 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * redesign disassembler interface so that we can reuse the same object multiple times
  
  this makes is possible to use the movement cache more than once by
  just keeping the object and the appended movement cache. This will
  make is possible (once the movement cache can cope with transformations
  to reuse the cache from older assemblies

Sat Aug 13 19:38:39 CEST 2005  Andreas Röver <roever@users.sourceforge.net>

  * include an inverse transformation array and replace the number of transformations with a constant

Thu Aug 11 19:26:17 CEST 2005  Andreas Röver <roever@users.sourceforge.net>

  * add an import function for puzzle solver files

Tue Aug  9 18:11:08 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * move the node definition into the disassembler files so that each disassembler can have its own
  
  this starts to get necessary because we will need to have a different
  node for the 4th disassembler because it may get rotations included
  and so it needs a 4th field specifying the rotation

Mon Aug  8 20:58:59 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * implement piece groups
  
  This allows you to put piece into groups that don't need to be
  taken apart to solve the disassembly of the puzzle. This is required
  for example for puzzles like "cube in cage" where the cage consists
  of 3 movable pieces that can not be taken apart.
  
  The gui currently alows you to increase the group number.
  
  Group number 0 is special, it means that the piece doesn't belong to
  any group at all and must be single in the disassembled puzzle

Fri Aug  5 12:30:18 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * add a function to calculate the inverse transformation

  * fix memory leaks and inconsisten new [] delete [] calls

Sun Jul  3 12:47:19 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * add a new disassembler
  
  this diassembler uses a cache to store the movement possibilities for
  each piece pair and relative position of this pair. The cache is then
  later on used to faster fill the matrix.
  
  This algorithm could be improved by keeping the cache over the period
  of solving one puzzle. This is escpecially useful when the puzzle has
  many assemblies (like Easy living)
  
  This algorithm speeds up complex puzzles like Pelikan Burr quite a bit
  (only 50% time left) but slows down puzzles with many simple assemblies
  as the cache has to be rebuild each time.

  * update to the voxel view class
  
  the new voxel view class uses multiple voxel spaces
  to view the complete result instead of one, this will
  be more flexible for the future: (color constraints
  in results)
  I also use the new functionality with the problem viewer
  right now

Sun Jun 19 17:24:30 CEST 2005  Andreas Röver <roever@users.sourceforge.net>

Sat Jun 18 19:20:02 CEST 2005  Andreas Röver <roever@users.sourceforge.net>

  * add an internal bounding box to the voxel space

Sat Jun 18 13:15:36 CEST 2005  Andreas Röver <roever@users.sourceforge.net>
  * use assembly in puzzle solutions instead of the assembly voxel space
  
  this saves a bit of space in the xml files, the usage of the assembly
  will also further go down into the different tasks then now, e.g
  the voxel space shoule really use the assembly instead of the current
  assemblyVoxel space.

  * Major Restructuring
  This patch does three major things:
  - restucture the puzzle oranisation into using problems with
    each problem using shapes from a puzzle wide defined list
  - use XML to save the puzzles
  - allow for color constraints

  * some cleanup

Sat Jan  1 13:13:36 CET 2005  Andreas Röver <roever@users.sourceforge.net>
  * specialize the voxel class
  
  the voxel class now has 2 subclasses one for each of the uses
  
  the assemlbyVoxel class is for assembled puzzles with a special
  value for empty voxels and the right numbers for the pieces
  
  the pieceVoxel contains the state and NEW also a field called color
  that will be used to constrain piece placement

Sat Jan  1 12:39:23 CET 2005  Andreas Röver <roever@users.sourceforge.net>
  * add frontend for cube puzzles

Sat Jan  1 11:36:33 CET 2005  Andreas Röver <roever@users.sourceforge.net>
  * const correctness

  * Split dancing link assembler from matrix creation
  
  This should allow to have serveral differen Puzzle piece types.
  For each type you can write a new frontend to assembler_0_c that
  handles the creation of the matrix and the generation of the solution
  
  currently only one frontend, for cube spaces, is defined
