These tests are checking composition outcode of window surfaces, child
and layered windows, as well as drawing API interactions.
They seem to consistently pass on the testbot but I'm not completely
sure about them. They are a bit brittle as screen capture and window
rendering is heavily dependent on the WM on Linux.
Still, I believe they are useful, and they show that we currently do
several things incorrectly so I'm sending them anyway.
