	Add a resize popup when resizing constrained
	windows, (bug 305564).

	* src/display.c:
	(meta_display_begin_grab_op),
	(meta_display_end_grab_op):
	* src/keybindings.c (process_keyboard_move_grab),
	(process_keyboard_resize_grab): Call
	meta_window_{begin,update,end}_wireframe convenience
	functions instead of the meta_effects counterparts.

	* src/display.h: keep track of old wireframe geometry to
	clean up xor popup on resize

	* src/effects.[ch] (meta_effects_begin_wireframe),
	(meta_effects_update_wireframe),
	(meta_effects_end_wireframe),
	(draw_xor_rect): take optional width and height arguments
	to show to user in resize popup. Draw resize popup if
	width and height >= 0 and wireframe isn't smaller than
	the popup would be.

	* src/screen.c (meta_screen_new): load a largish font for
	the resize popup

	* src/window.[ch]
	(meta_window_move_resize_internal): update
	wireframe resize popup when the window is resized.
	(meta_window_get_wireframe_geometry): new function to
	calculate the numbers to display in resize popup
	(meta_window_begin_wireframe),
	(meta_window_update_wireframe),
	(meta_window_end_wireframe): new functions to reduce
	repetitive wireframe code.  Functions handle updating
	wireframe and resize popup geometry.
	(update_move), (update_resize),
	(meta_window_refresh_resize_popup): remove fixme and
	add debug message.
