/** MaskPrimitive2D class
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.
