// the old code used to do it. The old colour scale was quite complex and
// although it looked like separate blocks of colour it was actually using
// a few solid colour blocks with interpolated colours. It was very tricky
// to get things to match when doing lookups and such though. So what we do
// is recreate the old scale and then query it to build a new scale of
// individual blocks of colour.
