Inherit visual from frame window so that metacity will work with the new

	Inherit visual from frame window so that metacity will work with
	the new compositing manager extension work by Keith on
	freedesktop.org, so that ARGB windows can be full
	alpha-transparent without a metacity frame getting drawn in the
	background.  In the long term, we need to actually set alpha
	values when drawing the frame so that it will really work; this is
	a stopgap solution.  Patch from Keith Packard; see Bug 126875.

	* src/frame.c (meta_window_ensure_frame): pass client visual to
	frame.

	* src/ui.[ch] (meta_ui_create_frame_window): add new xvisual
	parameter and use it to create new window.
