	* src/display.h (struct _MetaDisplay): track the last_xor_rect
	separately from the current window size, and then use that to
	paint the wireframe including the frame, and taking into
	account shaded windows.

	* src/window.c (meta_window_get_xor_rect): new function to compute
	the xor rect; it is not really 100% right, because it uses the
	frame dimensions from the window at the start of the move/resize.
	But probably won't break in practice.
