This allows for easily testing a compositor's damage tracking in all currently available configurations including wl_surface.buffer_transform, wl_surface.buffer_scale, and wl_viewport. It also includes a --rotating-damage that flag instructs the client to change the wl_surface.buffer_transform on every commit. This tests the compositor for proper handling of texture uploads even when the transform has changed but the buffer size hasn't.dev
