add a "fullscreen" semantic type; if a window requests the screen size

2001-08-19  Havoc Pennington  <hp@pobox.com>

	* src/window.c: add a "fullscreen" semantic type; if a window
	requests the screen size exactly, and is undecorated, and is not a
	desktop window, we consider it a fullscreen window and keep it on
	top.

	Totally untested.
