I think it would make more sense to volunteer to improve the
stereo_image_proc node, rather than putting that change into the
camera driver. It may be too late to add that to stereo_image_proc,
unfortunately. Though I would argue that adding a parameter won't
break anything downstream of image_pipeline.
