delete extra copy of find_argb_visual so things compile

2004-08-26  Havoc Pennington  <hp@redhat.com>

	* src/frame.c: delete extra copy of find_argb_visual so things
	compile

	* src/compositor.c (HAS_NAME_WINDOW_PIXMAP): copy the
	XCompositeNameWindowPixmap() stuff from xcompmgr, though I can't
	say I really know what it's supposed to help with (painting the
	window border?)
