Browse Source 
2002-12-09  Havoc Pennington  <hp@pobox.com>

	* AUTHORS: add myself here, bug #100789

	* src/display.c (meta_display_set_grab_op_cursor): drop
	PointerMotionHintMask

	* src/window.c (meta_window_handle_mouse_grab_op_event): don't use
	XQueryPointer, as we aren't using PointerMotionHint now

	* src/display.c (event_callback): rearrange a bit of code
	for slight speedup and clarity

	* src/window.c (update_resize)
	(meta_window_handle_mouse_grab_op_event): implement
	usage of the _METACITY_UPDATE_COUNTER
	(meta_window_handle_mouse_grab_op_event): fix code that
	used event->xbutton with a motion event

	* src/display.c (meta_display_open): add new atoms, and
	initialize Xsync if we have it
	(grab_op_is_resizing): new function
	(meta_display_begin_grab_op): create an alarm monitoring
	window's _METACITY_UPDATE_COUNTER
	(meta_spew_event): conditionalize this on WITH_VERBOSE_MODE
	and print alarm events.

	* src/window.c (meta_window_new): fetch _METACITY_UPDATE_COUNTER

	* configure.in (HAVE_XSYNC): check for Xsync extension
