Subject: steps preview: make step goal line change colour with target we also
 move the indicator line up in the z stack, as we want the line above the
 bars. This wasn't obvious before as the elements were all the same colour.
 The two processing functions, clamp and interpolateColors are probably not
 optimally placed in the code. These might move.
