             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.
