Detailed Description

Multiple ranges in one object.

This class combines multiple ranges in one object, providing a total, enclosing range for it.

You can use this class e.g. when updating views containing rectangular objects. Add each modified object to a B2DMultiRange, then test each viewable object against intersection with the multi range.

Similar in spirit to the poly-polygon vs. polygon relationship.

Note that comparable to polygons, a poly-range can also contain 'holes' - this is encoded via polygon orientation at the poly-polygon, and via explicit flags for the poly-range.
