Detailed Description
       The SoTextureCoordinateBundle class simplifies texture coordinate
       handling.

       It is unlikely that application programmers should need to know how to
       use this class, as it is mostly intended for internal use.

Constructor & Destructor Documentation
   SoTextureCoordinateBundle::SoTextureCoordinateBundle (SoAction *const
       action, const SbBool forRendering, const SbBool setUpDefault = TRUE)
       Constructor with action being the action applied to the node. The
       forRendering parameter must be TRUE if the bundle is to be used for
       sending texture coordinates to GL during rendering. The setUpDefault
       must be TRUE if default texture coordinates should be generated.

   SoTextureCoordinateBundle::~SoTextureCoordinateBundle ()
       Destructor.

Member Function Documentation
   SbBool SoTextureCoordinateBundle::needCoordinates (void) const
       Returns TRUE if texture coordinates are needed during rendering.

   SbBool SoTextureCoordinateBundle::isFunction (void) const
       Returns TRUE if a texture coordinate function should be used.

   const SbVec4f & SoTextureCoordinateBundle::get (const int index)
       Returns the texture coordinates at index index. Should only be used if
       SoTextureCoordinateBundle::isFunction() is FALSE.

   const SbVec4f & SoTextureCoordinateBundle::get (const SbVec3f & point,
       const SbVec3f & normal)
       Returns the texture coordinates based on point and normal. Should only
       be used if SoTextureCoordinateBundle::isFunction() is TRUE.

   void SoTextureCoordinateBundle::send (const int index) const [inline]
       Send texture coordinates to GL. Should only be used if
       SoTextureCoordinateBundle::isFunction() is FALSE.

   void SoTextureCoordinateBundle::send (const int index, const SbVec3f &
       point, const SbVec3f & normal) const [inline]
       Convenience function that will make it transparent to the rendering
       code if ordinary texture coordinates or function texture coordinates
       are used.

   SbBool SoTextureCoordinateBundle::needIndices (void) const
       Returns TRUE if isFunction() is TRUE, but the texture coordinate
       indices are needed either by bump mapping or by one of the other
       texture units.
