    00024  * Revision 1.17  2002/08/21 03:08:05  orlovich
    00025  *
    00026  * Cleanup:
    00027  * 1. Don't read unitialized variables all over the place
    00028  * 2. Make tiny mark distance setting actually matter.
    00029  * 3. Remove dead code that did nothing other than read uninitialized variables and write out
    00030  * somoe other ones noone actually used -- mark 3 methods with no effect as deprecated.
    00031  *
    00032  * Revision 1.16  2002/03/04 00:51:51  lunakl
    00033  * Keep BC changes (the patch is almost 100KiB of boring stuff
    00034  * ... anybody willing to review? ;) ).
    00035  *
    00036  * Revision 1.15  2000/11/29 11:52:59  mlaurent
    00037  * Fix draw marker when kruler is horizontal
    00038  *
    00039  * Revision 1.14  2000/09/12 17:48:02  mueller
    00040  * avoid compiler warning
    00041  *
    00042  * Revision 1.13  2000/06/05 21:31:45  gehrmab
    00043  * QFrame's 4th argument is no more
    00044  *
    00045  * Revision 1.12  2000/06/03 23:09:02  gehrmab
    00046  * Completely redesigned KRuler's API
    00047  *
    00048  * Revision 1.11  2000/04/15 16:16:56  habenich
    00049  * fixed bug with disappearing vertical text
    00050  * enabled offset drawing of begin and end marks
    00051  * implemented fixed ruler width when resizing widget
    00052  * implemented on/off switch for ruler pointer
    00053  * ruler label moves with beginning of ruler
    00054  *
    00055  * Revision 1.10  2000/01/17 19:07:59  bieker
    00056  * Made it more QT_NO_CAST_ASCII and QT_NO_ASCII_CAST safe (this is not 100 %
    00057  * yet).
    00058  *
    00059  * Revision 1.9  1999/05/10 12:59:04  kulow
    00060  * applied 90% of Hans's patch and tried to fix other stuff. Some classes
    00061  * (KAccel is a good example - libkab is even worse) mix string types so
    00062  * dramacticly, that I bet 70% of the runtime is spent in string conversion ;(
    00063  *
    00064  * Revision 1.8  1999/03/01 23:35:08  kulow
    00065  * CVS_SILENT ported to Qt 2.0
    00066  *
    00067  * Revision 1.7  1999/02/19 08:52:45  habenich
    00068  * ID und LOG tags included
    00069  *
