In practice, for KMS backend CRTC's, we cache the gamma in the monitor manager instance, so that anyone asking gets the pending or up to date value, instead of the potentially not up to date value if one queries after gamma was scheduled to be updated, and before it was actually updated. While this is true, lets still move the API to the MetaCrtc type; the backend specific implementation can still look up cached values from the MetaMonitorManager, but for users, it becomes less cumbersome to not have to go via the monitor manager.
