test case attempt 1

Here's a first attempt at a test case.

This program creates a window and gives it a shape that is partially outside
the window's bounding rectangle.

Unlike steam, the window is still decorated. I may need to fix that before
you'll get an identical result.

While I still don't see anything outside the window with compositing metacity,
moving the window creates a very interesting effect.
