Pass the backend instead of the compositor to the PipeWire output API create_head() method and increment the API version. That way the backend will not have to find the backend pointer from the compositor. This is trivial now, but in the multi-backend case would entail iterating over all backends to find the correct one. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
