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.
Unfortunately the scheme still has to be created by the daemon due to a
kernel bug, but once that is fixed, it would allow delayed spawning of
scheme daemons.
