I tested it (ran through many h,s,v triples and compared with previous 
algorithm), and it seems correct. It's a bit faster, but not as much as 
one would expect: on my computer the new version takes about 95% of the 
time that the old version took. I tried one more optimization, replacing 
the switch by a binary search, which took it down to 93-94% of the time 
of the old version. The attached patch contains both optimizations, and 
also my modifications to rgb_to_hsv().

I think your further optimizations would make a lot sense as an add-on.
