<para>
Pixmaps are offscreen drawables. They can be drawn upon with the
standard drawing primitives, then copied to another drawable (such as
a #GdkWindow) with gdk_draw_drawable(). The depth of a pixmap
a #GdkWindow). The depth of a pixmap
is the number of bits per pixels. Bitmaps are simply pixmaps
with a depth of 1. (That is, they are monochrome bitmaps - each
pixel can be either on or off).

* The source and destination drawables must have the same visual and
