I know this changed into pfMakeVecRotVecMat() in 2.0, but I'm seeing
some problems with the old version (legacy code - will convert it
eventually) in that when the two vectors are nearly parallel, the
rotations in the resulting matrix suddenly disappears. I'm guessing
that it's due to precision issues (using pfSinCos internally, etc.)
but was wondering if perhaps there was some known problem with it.
Did it get any better with 2.0? Or should I roll my own for this
case? (if so, anybody have a code fragment? ;)
