This matches the Linux DRM interface. With this I believe the only
divergence from the Linux DRM interface that would be a breaking change
to the in-tree users of the graphics api to change to the proper
interface is the use of the UPDATE_PLANE ioctl in the place of proper
modesetting interface. It should be possible to support this in
parallel to UPDATE_PLANE, so updating Orbital to the DRM interface
should now be possible. Orbital can be updated to the proper modesetting
interface once it is implemented.
