/* KW: A set of functions to convert unusual Color/Normal/Vertex/etc
 * calls to a smaller set of driver-provided formats.  Currently just
 * go back to dispatch to find these (eg. call glNormal3f directly),
 * hence 'loopback'.
 *
 * The driver must supply all of the remaining entry points, which are
 * listed in dd.h.  The easiest way for a driver to do this is to
 * install the supplied software t&l module.
