DefaultScreen() returns the screen number not Screen*

2002-05-09  Havoc Pennington  <hp@redhat.com>

	* src/frames.c (show_tip_now): DefaultScreen() returns the screen
	number not Screen*

	* src/frame.c (meta_frame_sync_to_window): immediately repaint
	frame whenever we resize it, if we're inside a grab operation.

	* src/frames.c (meta_frames_repaint_frame): new function

	* src/window.c (meta_window_new): initialize window's colormap
	(meta_window_notify_focus): install the colormap for a window when
	it gets focus, uninstall on unfocus.

	* src/window.h (struct _MetaWindow): store window's colormap

	* src/display.c (event_callback): note changes to window colormap

	* src/frame.c (EVENT_MASK): add ColormapChangeMask
