Added the Colormap component.

* The Colormap component is a simple rect with a texture mapped
  that displays a ColorScale with a fixed number of samples. This
  number of samples is exported as a member const, which is used
  on other components (such as VoronoiSplat).
* The texture mapping is reflecting the colormap lookup used in
  VoronoiSplat.
* The ColorScale class now has a method for sampling the color
  scale and outputs the samples to iterator-style objects,
  providing easy intergration with existing code.
