Do you think we'll need a compositor fallback?
*If* we do have a compositor fallback, then I don't see the point of a DRM
specific codepath, it's not going to have any slower having a transform in
painting, and will just result in one code path not getting tested.
To mostly answer my own question:
In hwcomposer, it seems we have a transform attribute on the layer.
For nested wayland we can set a transform on our wl_surface.
For FBDev or nested in X, I don't think we can. But probably don't care?

why don't we use DRM_MODE_ROTATE_0 for the values?
