// Description : This template class is a special kind of AnimChannel
|
|
// that always returns just one fixed value. It is a
|
|
// special channel, in that it need not be assigned
|
|
// within a hierarchy. It may stand alone, so that it
|
|
// may be created on-the-fly for parts that need default
|
|
// anims to bind against.
