Return true from getValueExtents always, just with no unit in the case where we don't have a nice neat scale. This should preserve the property of preventing other layers auto-aligning to us, while also ensuring we don't get overlooked for the purposes of drawing our own scale in a situation where a scale-less layer is on top of us
