Ha!  Some help that is -- I already had to figure it out myself. :-)

They are not used for rendering at all.  They are aparently used to make the
wireframe Tri-View faster, and to do some modeling tasks like extrusion
and "spinning".  To render the triangles you need only the point and polygon
information.

| 	byte fraction?

It doesn't matter -- their absolute mangnitudes don't mean anything.
