Turn the poses supplied with a composition layer into the poses the compositor wants.

Parameters

	log	logger
	sess	session
	spc	space that pose_ptr is supplied in
	pose_ptr	pose supplied with layer
	timestamp	timestamp for pose
[out]	out_pose	Resulting view-space pose

Returns

true if successfully transformed into a view space pose
