Subject: add opaque minimize/shade feature. The wireframe seemed kind of
 confusing

2001-08-06  Havoc Pennington  <hp@pobox.com>

	* src/effects.c: add opaque minimize/shade feature.  The wireframe
	seemed kind of confusing and unclear from a UI standpoint.
	I know, I know. The bloat begins here.

	Also, we don't need to grab the server during opaque min/shade,
	which has some nice implications.

	* src/ui.c: Add features to render a window with an image in it,
	and also wrap pixbuf_from_drawable

	* src/effects.c (meta_effects_draw_box_animation):
	modify to be smoother (at least theoretically) by
	syncing to current time and "dropping frames"
	as appropriate.

	* src/window.c (meta_window_shade): draw animation
	for shading too
