One thing that I would expect to cause trouble is the precision with
which you'll need to represent intermediate results when interpolating
vertex attributes.  32-bit fixed point is marginal for 16-bit
interpolants.  You might need to go to 64-bit fixed or
double-precision float.  Check out the math in tritemp.h.
