rectangle_properties - description of the Rectangle entity properties

### Description

The Rectangle entity is a leaf of the graphics entities hierarchy. This entity defines the parameters for rectangles and filled rectangles.
- visible: This field contains the `visible` property value for the entity . It should be `"on"` or `"off"` . By default, the rectangle is visible, the value's property is `"on"`. If `"off"` the rectangle is not drawn on the screen.
- data: This property is to return the coordinates of the upper-left point of the rectangle and its width and height in the data units of the axes. The result is the matrix `[xleft,yup;width,height]`
- line_style: The `line_style` property value should be an integer in [0 9]. 0 stands for solid the other value stands for a selection of dashes.
- thickness: This field contains the line `thickness` property. Its value should be a positif integer.
- mark_mode: If `mark_mode` property is `"on"` and the rectangle is represented by a mark drawn at each corners. points. If the property property is to `"off"` the rectangle is represented using lines or paint surface.
- mark_style: The `mark_style` property value is used to select the type of mark to use when `mark_mode` property is `"on"` . It's value should be an integer in [0 9] which stands for: dot, plus, cross, star, diamond fill, diamond, triangle up, triangle down, trefle and circle.
- mark_size: The `mark_size` property is used to select the type of size of the marks when `mark_mode` property is `"on"` . Its value should be an integer in [0 5] whith stands for 8pt, 10pt, 12pt, 14pt, 18pt and 24pt.
- foreground: This field contains the default `foreground` property used to draw or to fill the rectangle. Its value should be a color index (relative to the current colormap).
- fill_mode: If `fill_mode` property value is `"on"` , the rectangle is filled with the foreground color, the `mark_mode` must also have the value `"off"`. if not and the value's property is `"off"` only the shape of the rectangle is drawn using the foreground color.
- clip_state: This field contains the `clip_state` property value for the rectangle. It should be :
- `"off"` this means that the rectangle is not clipped.
- `"cliprf"` this means that the rectangle is clipped outside the Axes box.
- `"on"` this means that the rectangle is clipped outside the rectangle given by property clip_box.
- clip_box: This field is to determinate the `clip_box` property. By Default its value should be an empty matrix if clip_state is "off". Other cases the vector `[x,y,w,h]` (upper-left point width height) defines the portions of the rectangle to display, however `clip_state` property value will be changed.
- parent: This field contains the handle of the parent. The parent of the rectancle entity should be of the type `"Axes"` or `"Agregation"`.

### Exemples

       set("figure_style","new") //create a figure
       a=get("current_axes");//get the handle of the newly created axes
       a.data_bounds=[-2,-2,2,2];

       xrect(-1,1,2,2)

       r=get("hdl");//get handle on current entity (here the rectangle entity)
       r.type
       r.parent.type
       r.foreground=13;
       r.line_style=2;
       r.fill_mode="on";
       r.clip_box=[-1 1;1 1];
       r.clip_state="off"
       r.data(:,2)=[1/2;1/2];
       r.data(:,1)=[1/2;1/2];
