//       Class : AnimChannelMatrixXfmTable
// Description : An animation channel that issues a matrix each frame,
//               read from a table such as might have been read from
//               an egg file.  The table actually consists of nine
//               sub-tables, each representing one component of the
//               transform: scale, rotate, translate.
