xcompmgr was a proof of concept, last release was in 2005, also a bit
slow / cpu intensive with even a minimal 1pix blur shadow, and it has
some issues (root window going black and keeping old data, gtk1 apps
requiring tricks). What I have heard is that the prefered approach is
to combine with wm to reduce overhead and be more featureful.
