Jeff Smith cb908a7840 glamor: tidy up some gradient color formulas 
- Avoid some needlessly complex equations for calculating the color at a
  point in a gradient field.
- Avoid calculating certain values multiple times.
- Use similar variable names across the two versions of the get_color
  function where practical.
