handle the client having a shape mask, fixes #101806

Browse Source 
2003-01-05  Havoc Pennington  <hp@pobox.com>

	* src/frames.c (meta_frames_apply_shapes): handle
	the client having a shape mask, fixes #101806

	* src/core.c (meta_core_get_client_xwindow): new function

	* src/frame.c, src/frame.h: keep a flag for whether we need to
	update the frame shape

	* src/window.c (meta_window_new): select for ShapeNotify

	* src/display.h, src/display.c: actually query the shape
	extension, instead of just using it all over the place.

	* src/prefs.c (update_application_based): don't let people turn on
	application_based, as it just causes funky bugs. We can reenable
	the pref when/if it ever does something useful.
