-- Pixmaps are off-screen drawables. They can be drawn upon with the standard
-- drawing primitives, then copied to another drawable (such as a Gdk_Window)
-- with Gdk.Drawable.Draw_Drawable. 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).
-- See Gdk.Pixmap for more details on pixmap handling.
