// Class : EggJointPointer

|
// Description : This is a base class for EggJointNodePointer and
|
|
// EggMatrixTablePointer. It stores a back pointer to
|
|
// either a <Joint> entry or an xform <Table> data, and
|
|
// thus presents an interface that returns 1-n matrices,
|
|
// one for each frame. (<Joint> entries, for model
|
|
// files, appear the same as one-frame animations.)
