Beginning of new layer that abstracts transition effects.

Browse Source 
Mon May 22 17:35:52 2006  Søren Sandmann  <sandmann@redhat.com>

	* src/effects.[ch]: Beginning of new layer that abstracts
	transition effects.

	New functions:
	(meta_push_effect_handler): Install an effect handler
	(meta_pop_effect_handler): Remove last effect handler
	(meta_effect_run_minimize): Create a minimize effect and pass it
	to the handler.
	(meta_effect_end): Called by handler when the effect is finished.

	* src/compositor.c: Move explosion code form there to src/c-window.c.

	* src/c-screen.c: Delete explosion related code.
