	* src/frames.c (meta_frames_init): disable automatic GTK double
	buffering, since it resulted in gigantic backing pixmaps the size
	of the whole screen.
	(meta_frames_paint_to_drawable): change to take a region argument;
	punch the client area out of the expose region, then iterate over
	rectangles in the region and draw each, manually doing
	begin_paint_rect. Results in 4 long thin backing pixmaps
	per frame repaint, instead of one large backing pixmap.
	Suggested by Owen.
