648 * successive primitives layed out linearly in the vertex arrays.
649 * Unless the vertex arrays are all in a VBO (or locked as with
650 * CVA), the OpenGL semantics imply that we need to re-read or
651 * re-upload the vertex data on each draw call.
653 * In the case of hardware tnl, we want to avoid starting the

655 * increasing amount of not-used vertex data. Worse - in the
656 * software tnl module, all those vertices might be transformed and
657 * lit but never rendered.
659 * If we just upload or transform the vertices in start..end,
660 * however, the indices will be incorrect.
662 * At this level, we don't know exactly what the requirements of
663 * the backend are going to be, though it will likely boil down to
666 * 1) Do nothing, everything is in a VBO and is processed once
669 * 2) Adjust the indices and vertex arrays so that start becomes

673 * for the latter case elsewhere.
