//       Class : EggXfmAnimData
// Description : Corresponding to an <Xfm$Anim> entry, this stores a
//               two-dimensional table with up to nine columns, one
//               for each component of a transformation.  This is an
//               older syntax of egg anim table, not often used
//               currently--it's replaced by EggXfmSAnim.
