 * NAME:        RE_OGLVertex.h ( RE Library, C++)
 *
 * COMMENTS:    Vertex handling class.  This is to handle the two states for
 *              vertex output (convex & concave).  By having two classes for
 *              vertices, we simplify the code by eliminating a comparison on
 *              every vertex.
