Add a shortcut if the window and the current clip_region doesn't overlap.

2001-02-13  Alexander Larsson  <alla@lysator.liu.se>

	* gdk/linux-fb/gdkdrawable-fb2.c (gdk_fb_clip_region):
	Add a shortcut if the window and the current clip_region doesn't
	overlap. This is needed when there are a lot of windows in a
	window. The layout test in testgtk is a good test.

	* gdk/linux-fb/gdkwindow-fb.c:
	Whitespace fix.
