Hmm, why is this special to virtual hw?

Hmm, that'll either make drm_mode_cursor_atomic a big cut+pasted
function, or need quite some refactoring to move common code into
functions callable from both drm_mode_cursor_atomic
+drm_mode_cursor_universal ...
Why attach the hotspot to the plane? Wouldn't it make more sense to
make it a framebuffer property?
cheers,
Gerd
