-/* Helper for drivers which find themselves rendering a range of
- * indices starting somewhere above zero. Typically the application
- * is issuing multiple DrawArrays() or DrawElements() to draw
- * successive primitives layed out linearly in the vertex arrays.
- * Unless the vertex arrays are all in a VBO, the OpenGL semantics
- * imply that we need to re-upload the vertex data on each draw call.
- * In that case, we want to avoid starting the upload at zero, as it
- * 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
- * of zero.
