Browse Source 
2007-04-08  Elijah Newren  <newren gmail com>

	Fix move/resize events in relation to combinations of
	ConfigureRequest and WM_NORMAL_HINTS change notifications (plus a
	few code cleanups).  Fixes #426519.

	* src/window.c (meta_window_move_resize_now):
	move to the user_rect position, not some weird combination of rect
	and user_rect

	* src/window.c (meta_window_configure_request):
        set user_rect in response to ConfigureRequest events (after the
	ConfigureRequest values have been constrained) and add a big
	comment explaining this change, remove unused only_resize variable
	and irrelevant huge FIXME comment about it

	* src/window.[ch] (meta_window_get_client_root_coords):
	new function

	* src/display.c (meta_display_begin_grab_op):
	* src/keybindings.c (process_keyboard_move_grab):
	* src/window.c (meta_window_unmaximize,
	  meta_window_move_resize_internal, meta_window_begin_wireframe,
	  update_move, meta_window_refresh_resize_popup,
	  warp_grab_pointer)
	combine multi-step client rect root coord setting into a single
	function call to meta_window_get_client_root_coords()
