+/* 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 vtxfmt.h.  The easiest way for a driver to do this is to
+ * install the supplied software t&l module.
