Detailed Description

The set of attributes that may be applied to vertices as well as polygons, such as surface normal and color.

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.
