00025 //       Class : NodeVertexTransform
00026 // Description : This VertexTransform gets its matrix from the
00027 //               Transform stored on a node.  It can also compose its
00028 //               node's transform with another VertexTransform,
00029 //               allowing you to build up a chain of
00030 //               NodeVertexTransforms that represent a list of
00031 //               composed matrices.
