Detailed Description
       The SoConvexDataCache class is used to cache convexified polygons.

       SoConvexDataCache is used to speed up rendering of concave polygons by
       tessellating all polygons into triangles and storing the newly
       generated primitives in an internal cache.

       This class is not part of the original SGI Open Inventor v2.1 API, but
       is a Coin extension.

Member Enumeration Documentation
   enum SoConvexDataCache::Binding
       The Binding enum is used to specify bindings. Binding applies to
       normals, materials and texture coordinates.

Constructor & Destructor Documentation
   SoConvexDataCache::SoConvexDataCache (SoState *const state)
       Constructor with state being the current state.

   SoConvexDataCache::~SoConvexDataCache () [virtual]
       Destructor.
