	* gdk/quartz/gdkdrawable-quartz.c:
	(gdk_quartz_drawable_get_context),
	(gdk_quartz_drawable_release_context):
	* gdk/quartz/gdkeventloop-quartz.c: (gdk_event_prepare),
	(gdk_event_check), (gdk_event_dispatch), (poll_func):
	* gdk/quartz/gdkwindow-quartz.h: Replace the autorelease pools
	used for each drawing context and in prepare, dispatch and poll
	with one that exists across each main loop iteration. Fixes leaks
	on leopard and protects against future leaks introduce when the
	underlying system changes again (bug #492977).
