2008-02-24  Richard Hult  <richard imendio com>

	* gdk/quartz/gdkprivate-quartz.h:
	* gdk/quartz/gdkeventloop-quartz.c: (got_fd_activity), (poll_func):
	Use the subtype field for the custom event that is used to wake up
	the mainloop so we can have other custom event types.

	* gdk/quartz/gdkevents-quartz.c:
	(_gdk_quartz_events_trigger_crossing_events):
	* gdk/quartz/gdkwindow-quartz.c: (show_window_internal): Create
	crossing events after showing a window if necessary, to work
	around problems with the tracking rect API.
