/** MaskPrimitive2D class
This is the central masking primitive. It's a grouping
primitive and contains a PolyPolygon which defines the visible
area. Only visualisation parts of the Child primitive sequence
inside of the mask PolyPolygon is defined to be visible.
This primitive should be handled by a renderer. If it is not handled,
it decomposes to it's Child content, and thus the visualisation would
contaiun no clips.
The geometrc range of this primitive is completely defined by the Mask
PolyPolygon since by definition nothing outside of the mask is visible.
