I just stumbled across this problem. I'll need a `sfs.util.normalize_vector()`. Please do not remove, but rename ;)

`util.direction_vector(point1, point2)` would be very handy, if not necessary. Or I would introduce an optional "base" to `normalize_vector()` . The default would be 0. Please have a look at this:...

Sorry, I think the accurate term is "initial point" of a vector. Typically our direction vectors are normalized.

I was facing the same problem. Also the API seems to change quite frequently... Eventually I gave up on chasing them (couldn't fix to a specific old version for other...
