-/*
- * Notes on primitive restart:
- * The code below is used when the gallium driver does not support primitive
- * restart itself.  We map the index buffer, find the restart indexes, unmap
- * the index buffer then draw the sub-primitives delineated by the restarts.
- * A couple possible optimizations:
- * 1. Save the list of sub-primitive (start, count) values in a list attached
- *    to the index buffer for re-use in subsequent draws.  The list would be
- *    invalidated when the contents of the buffer changed.
- * 2. If drawing triangle strips or quad strips, create a new index buffer
- *    that uses duplicated vertices to render the disjoint strips as one
- *    long strip.  We'd have to be careful to avoid using too much memory
- *    for this.
- * Finally, some apps might perform better if they don't use primitive restart
- * at all rather than this fallback path.  Set MESA_EXTENSION_OVERRIDE to
- * "-GL_NV_primitive_restart" to test that.
