/**
* This class stores miscellaneous rendering properties that is associated
* with geometry, and which may be set on the geometry primitive level, on the
* group above it, or indirectly via a texture. It's intended to be a base
* class for egg objects that can have these properties set.
*
* This class cannot inherit from EggObject, because it causes problems at the
* EggPolygon level with multiple appearances of the EggObject base class.
* And making EggObject a virtual base class is just no fun.
