Yeah, I assumed so.  I'm not good enough with rotations to actually fix 
the vergence code, and I figured that if it's been "broken" this long, 
people have come to expect the old behavior, and the safest thing to do 
for a minor point release hotfix is to just revert back to the old way 
(hence my patch).

Since 1.18 is on the plate now, it may be a better time to actually make 
it work the way the original coder intended.

If someone good with rotations can spare the time to explain, how can 
you have a version of SetQuat that takes a floating point angle and a 
Vector3 and come out with a single unambiguous answer?

It seems to me that would only define a conic section, or if it were 
axis aligned, two possible orientations.
