This structure collects together the different combinations of transforms and blend amounts used by a GeomVertexData, to facilitate computing dynamic vertices on the CPU at runtime.
Each vertex has a pointer to exactly one of the entries in this table, and each entry defines a number of transform/blend combinations.
This structure is used for a GeomVertexData set up to compute its dynamic vertices on the CPU. See TransformTable for one set up to compute its dynamic vertices on the graphics card.

int TransformBlendTable::add_blend | ( | const TransformBlend & | blend | ) |
Adds a new blend to the table, and returns its index number.
If there is already an identical blend in the table, simply returns that number instead.
