+
+            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.
