        /** FillGraphicPrimitive2D class

            This class defines a bitmap filling for a rectangular area. The
            Range is defined by the Transformation, the fill by the FillGraphicAttribute.
            There, the fill consists of a Bitmap (not transparent) defining the fill data
            and a Point/Vector pair defining the relative position/size [0.0 .. 1.0]
            inside the area where the bitmap is positioned. A flag defines then if this
            is tiled or not.

            Renderers should handle this primitive; it has a geometrically correct
            decomposition, but on pixel outputs the areas where the tiled pieces are
            aligned tend to show up (one overlapping or empty pixel)
