+ * 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.
