+ This is the central masking primitive. It's a grouping
+ primitive and contains a tools::PolyPolygon which defines the visible
+ area. Only visualisation parts of the Child primitive sequence
+ inside of the mask tools::PolyPolygon is defined to be visible.
+
+ This primitive should be handled by a renderer. If it is not handled,
+ it decomposes to its Child content, and thus the visualisation would
+ contain no clips.
+
+ The geometry range of this primitive is completely defined by the Mask
+ tools::PolyPolygon since by definition nothing outside of the mask is visible.
