use t_vertex.c - try 3

quasi-native vertex format.

we use the following hack in attribute emission:

   /* The TNL module requires that the first attribute is _TNL_ATTRIB_POS, 
    * at the same time, the mach64 native vertex format has the XYZW coords 
    * at non-consecutive positions spread inside the vertex.
    *
    * We reserve space for the XYZW coords with EMIT_PAD's and when the vertex 

    * is copied to the vertex buffer for submission to the card, we use the 
    * _TNL_ATTRIB_POS values to fill in the pads reserved for XYZW and discard 

    * the first 4 bytes of the vertex.
    */
