Elijah Newren 81e32cfa32 Clean up event mask handling and meta_create_offscreen_window, to prevent
2007-03-31  Elijah Newren  <newren gmail com>

	Clean up event mask handling and meta_create_offscreen_window, to
	prevent nasty metacity/gdk interactions causing hangs. See #354213.

	* src/screen.[ch] (meta_create_offscreen_window):
	* src/display.c (meta_display_open):
	* src/screen.c (meta_screen_new):
	Add a valuemask parameter to meta_create_offscreen_window
	
	* src/display.c (meta_display_open):
	make it explicit that we can't rely on PropertyNotify events for
	the leader_window due to nasty metacity/gdk interaction

	* src/session.c (warn_about_lame_clients_and_finish_interact):
	remove cut-and-paste code for timestamp pinging and just call
	meta_display_get_current_time_roundtrip
