DirectShapeLibrary is used to store pre-created geometry for further referencing via the definition/instance mechanism.
It is not persistent: the scope of a library object is usually a single data creation session.
DirectShape::createGeometryInstance and DirectShape::CreateElementInstance will use the current DirectShapeLibrary to
look up the definitions.

Remarks
There are two ways to add a definition to the library. The first is to add the definition as an array of geometry objects.
A DirectShape created as an instance of that definition will hold a copy of predefined geometry, transformed as requested.
If the definition was added as a DirectShapeType, a DirectShape object created as an instance of that definition will reference the type.
Its geometry would be an instance of type geometry.
