51 : : This class defines a gradient filling for a rectangular area. The

53 : :
54 : : The decomposition will deliver the decomposed gradient, e.g. for an ellipse
55 : : gradient the various ellipses in various color steps will be created.
56 : :
57 : : I have added functionality to create both versions of filled decompositions:
58 : : Those who overlap and non-overlapping ones. The overlapping version is the
59 : : default one since it works with and without AntiAliasing. The non-overlapping
60 : : version is used in the MetafilePrimitive2D decomposition when the old XOR
