the given color (and thus decomposes to a filled polygon). This
makes it a view-depnendent primitive by definition. It only has
a valid decomposition if a valid Viewport is given in the
ViewInformation2D at decomposition time.
It will try to buffer it's last decomposition using maLastViewport
to detect changes in the get2DDecomposition call.
