width x height region of src at coordinates (xsrc,
ysrc) to coordinates (xdest, ydest) in drawable.
width and/or height may be given as -1, in which case the entire
src drawable will be copied.gdkDrawDrawable(object, gc, src, xsrc, ysrc, xdest, ydest, width, height)gc are not used for this operation, but notably the
clip mask or clip region will be honored.
The source and destination drawables must have the same visual and
colormap, or errors will result. (On X11, failure to match
visual/colormap results in a BadMatch error from the X server.)
A common cause of this problem is an attempt to draw a bitmap to
a color drawable. The way to draw a bitmap is to set the bitmap as
the stipple on the GdkGC, set the fill mode to GDK_STIPPLED, and
then draw the rectangle.
