	* src/screen.c (meta_screen_get_xinerama_for_window):
	short-circuit the "only one xinerama" case, and use outer rect of
	window instead of window->rect, so we get root window coords.

	* src/theme.c (meta_frame_layout_get_borders): if fullscreen all
	frame edges are zero-width.

	* src/frame.c (meta_frame_get_flags): init fullscreen flag.

	* src/common.h (enum): add META_FRAME_FULLSCREEN frame flag

	* src/place.c: fix up calls to meta_window_get_work_area

	* src/window.c (meta_window_get_work_area): add an arg for whether
	the work area is for the screen or the xinerama subscreen.
	(constrain_position): fix up calls to meta_window_get_work_area
	(constrain_size): ditto

	* src/screen.c (meta_screen_new): add METACITY_DEBUG_XINERAMA
	environment variable which simulates xinerama on a single head.
