I just noticed that it was not wise of me to remove the vnormalize()
expressions from the 4 first lines in the Triangle2Triangle_Trans()
macro. Here's how these lines should be:

#local vFx = vnormalize(pA1 - pA0);
#local vLx = vnormalize(pB1 - pB0);
#local vFy = vcross(vFx, vnormalize(pA2 - pA0));
#local vLy = vcross(vLx, vnormalize(pB2 - pB0));
