Log:
2008-01-10  Richard Hult  <richard imendio com>

	* gdk/quartz/gdkwindow-quartz.c: (show_window_internal),
	(gdk_window_hide), (move_resize_window_internal): Move the
	tracking rect workaround from here...

	* gdk/quartz/GdkQuartzWindow.c:
	* gdk/quartz/GdkQuartzWindow.h: ...to here, and ignore window
	movements during showing/hiding operations. Fixes bug #508516.
