void env_motion_channel_input_and_consume_pyr	(	struct env_motion_channel *	chan,
		const char *	tagName,
		const struct env_params *	envp,
		const struct env_math *	imath,
		const struct env_dims	inputdims,

	)

env_motion_channel only requires luminosity input

for efficiency, the motion channel takes ownership of the lowpass5 pyramid (rather than needing to make a copy of it), so that after this function the lowpass5 argument will point to an empty pyramid
