xshape+xcomposite

[Deron Johnson]

If you need help getting a composite manager to work with the SHAPE
extension I recommend that you contact Amir Bukhari
(ufz6 at rz.uni-karlsruhe.de). He got the shape extension working for
Looking Glass (modulo a few minor bugs) and perhaps he could offer you
some advice.
