- * Unless the vertex arrays are all in a VBO, the OpenGL semantics

- * will mean every draw call uploads an increasing amount of not-used

- * vertex data.  Worse - in the software tnl module, all those

- * vertices will be transformed and lit.

- *

- * If we just upload the new data, however, the indices will be

- * incorrect as we tend to upload each set of vertex data to a new

- * region.  

- *

- * This file provides a helper to adjust the arrays, primitives and

- * indices of a draw call so that it can be re-issued with a min_index
