830/**
831 * Transform/Clip/Lighting interface
832 *
833 * Drivers present a reduced set of the functions possible in
834 * glBegin()/glEnd() objects.  Core mesa provides translation stubs for the
835 * remaining functions to map down to these entry points.
836 *
837 * These are the initial values to be installed into dispatch by
838 * mesa.  If the T&L driver wants to modify the dispatch table
839 * while installed, it must do so itself.  It would be possible for
840 * the vertexformat to install its own initial values for these
841 * functions, but this way there is an obvious list of what is
842 * expected of the driver.
843 *
844 * If the driver wants to hook in entry points other than those
845 * listed, it must restore them to their original values in
846 * the disable() callback, below.
