We can skip to the end of _mesa_update_state_locked() if only the _NEW_LINE flag is set since none of the derived state depends on it (just like _NEW_CURRENT_ATTRIB). Note that we still call the ctx->Driver.UpdateState() function, of course. v2: use bitmask-based test, per Eric. Reviewed-by: Eric Anholt <eric@anholt.net>
