  37             This primitive defines single,discrete 'pixels' for the given
  38             positions in the given color. This makes it view-dependent since
  39             the logic size of a 'pixel' depends on the view transformation.
  40
  41             This is one of the non-decomposable primitives, so a renderer
  42             should process it (Currently it is only used for grid visualisation,
  43             but this may change).
