  32             This primitive defines single,discrete 'pixels' for the given
  33             positions in the given color. This makes it view-dependent since
  34             the logic size of a 'pixel' depends on the view transformation.
  35
  36             This is one of the non-decomposable primitives, so a renderer
  37             should process it (Currently it is only used for grid visualisation,
  38             but this may change).
