This class defines functions that allow entities to vectorize themselves.

\remarks
|
Vectorization with the methods of this class are viewport independent.
|
For viewport specific vectorization, use subViewportDraw() instead of subWorldDraw().
|
|
An OdGiWorldGeometry object is part of the OdGiWorldDraw argument passed to the subWorldDraw()
|
method of an entity.
|
|
Model coordinates are applied to all geometry in this class except for setExtents().
