/** 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.
