A class that handles the rendering of the remote display and inform of its updates.
The creation of the main graphic buffer is signaled with "display-primary-create".
The update of regions is notified by "display-invalidate" signals.
struct SpiceDisplayChannel;
The SpiceDisplayChannel struct is opaque and should not be accessed directly.
