Subject: [PATCH] Remove invalidate_maybe_recurse and process_updates from the
 paintable interface

Replace them with two new functions
_gdk_windowing_{before,after}_process_all_updates() that are called
around the guts of gdk_window_process_all_updates(). Add empty ones
for X11 (nothing more needed), quartz ones will be implemented next.
