Todo:

Update expgain independently for each camera like in WMR

rift_s_camera_create()

struct rift_s_camera * rift_s_camera_create	(	struct xrt_prober *	xp,
		struct xrt_frame_context *	xfctx,
		const char *	hmd_serial_no,
		struct os_hid_device *	hid,
		struct rift_s_tracker *	tracker,

Todo:

Should we try to switch to an explicit 3dof mode?
