//       Class : EggAttributes
// 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.
