/** FillGradientPrimitive2D class
This class defines a gradient filling for a rectangular area. The
Range is defined by the Transformation, the gradient by the FillGradientAttribute.
The decomposition will deliver the decomposed gradient, e.g. for an ellipse
gradient the various ellipses in various color steps will be created.
I have added functionality to create both versions of filled decompositions:
Those who overlap and non-overlapping ones. The overlapping version is the
default one since it works with and without AntiAliasing. The non-overlapping
version is used in the MetafilePrimitive2D decomposition when the old XOR
paint was recorded.
