/* Types of windows.
 *   Root: There is only 1 root window and it is initialized
 *	   at startup. Creating a window of type GDK_WINDOW_ROOT
 *	   is an error.
 *   Toplevel: Windows which interact with the window manager.
 *   Child: Windows which are children of some other type of window.
 *	    (Any other type of window). Most windows are child windows.
 *   Dialog: A special kind of toplevel window which interacts with
 *	     the window manager slightly differently than a regular
 *	     toplevel window. Dialog windows should be used for any
 *	     transient window.
 *   Pixmap: Pixmaps are really just another kind of window which
 *	     doesn't actually appear on the screen. It can't have
 *	     children, either and is really just a convenience so
 *	     that the drawing functions can work on both windows
 *	     and pixmaps transparently. (ie. You shouldn't pass a
 *	     pixmap to any procedure which accepts a window with the
 *	     exception of the drawing functions).
 *   Foreign: A window that actually belongs to another application
