            This primitive defines single,discrete 'pixels' for the given
            positions in the given color. This makes it view-dependent since
            the logic size of a 'pixel' depends on the view transformation.

            This is one of the non-decomposable primitives, so a renderer
            should process it (Currently it is only used for grid visualisation,
            but this may change).
