A general polygon has a shape hint associated with it that specifies the shape of the general polygon. A general polygon's shape hint may be used by a renderer to optimize drawing the polygon.
typedef enum TQ3GeneralPolygonShapeHint {
kQ3GeneralPolygonShapeHintComplex,
kQ3GeneralPolygonShapeHintConcave,
kQ3GeneralPolygonShapeHintConvex
} TQ3GeneralPolygonShapeHint;
