// Description : Stores the total set of VertexTransforms that the

|
// vertices in a particular GeomVertexData object might
|
|
// depend on.
|
|
//
|
|
// This structure is used for a GeomVertexData set up to
|
|
// compute its dynamic vertices on the graphics card.
|
|
// See TransformBlendPalette for one set up to compute
|
|
// its dynamic vertices on the CPU.
|
|
//
|
|
// This is part of the experimental Geom rewrite.
