(int canvas, int xpos, int ypos, int xsize, int ysize, int flag)
Description: Creates a
rectangle on the specified canvas on coordinates (xpos, ypos) with
width 'xsize' and height 'ysize'. If the flag contains a '0' then the

default the color of the figure will be black, unless the color is set
with the command visio::canvas_fg_color.
