From: Thierry Reding <treding@xxxxxxxxxx>
This small program allows universal planes to be tested. Currently this
isn't very flexible because it allows only the first plane of a given
type to be tested on the first CRTC. However it should be simple to
extend this with some additional command-line arguments.
