2007-06-01  Richard Hult  <richard@imendio.com>

	* gdk/quartz/gdkevents-quartz.[ch]: Make function naming
	consistent for the various functions that retrieve data from an
	event.

	* gdk/quartz/gdkprivate-quartz.h: 
	* gdk/quartz/gdkwindow-quartz.[ch]: Remove the now unused
	_gdk_quartz_window_find_child_by_point() function.
