You somehow have to put the two forward- and up-vectors into relation. I
thought that maybe projecting both forward vectors onto a plane, get the
angle, rotate the vectors and then calculate new angles for the up-vector
might be a way to go. You've probably got something faster up your sleeve,
the way you phrase it...
