baldurk 4a3217fdcc Be cheeky and pack extra overdraw levels into slight colour changes ...

* Since we decode the visual colours into an integer by looking them up
  in the overdraw ramp rather than re-running to get an integer return,
  we make some invisibly subtly different colours above the highest
  overdraw colour, and use these to tell overdraw levels above 20.
