To make a frame clock tick as long as any of the associated surfaces expect to receive ticks, make the surfaces inhibit freezing the clock, instead of directly tell the frame clock to freeze itself. This makes it so that as long as any surface using a certain frame clock is not frozen (e.g. just received a frame event from the display server), the frame clock will not be frozen. With this, the frame clock is initiated as frozen, and won't be thawed until any surface inhibits freeze. It will be frozen again, when every surface has that previously inhibited freeze uninhibited freeze.
