41             This class defines a hatch filling for a rectangular area. The
42             Range is defined by the Transformation, the hatch by the FillHatchAttribute.
43             If the background is to be filled, a flag in FillHatchAttribute is set and
44             the BColor defines the background color.
45 
46             #120230# This primitive is now evtl. metric dependent due to the value
47             MinimalDiscreteDistance in the FillHatchAttribute if the value is not zero.
48             This is used for a more appealing, VCL-like visualisation by not letting the
49             distances get too small between lines.
50 
51             The decomposition will deliver the hatch lines.
