        /** FillHatchPrimitive2D class

            This class defines a hatch filling for a rectangular area. The
            Range is defined by the Transformation, the hatch by the FillHatchAttribute.
            If the background is to be filled, a flag in FillHatchAttribute is set and
            the BColor defines the background color.

            #i120230# This primitive is now evtl. metric dependent due to the value
            MinimalDiscreteDistance in the FillHatchAttribute if the value is not zero.
            This is used for a more appealing, VCL-like visualisation by not letting the
            distances get too small between lines.

            The decomposition will deliver the hatch lines.
