Fix problems with HSV->RGB conversion
Fix problems with HSV->RGB conversion

* Wasn't convering the expanded 0->360 value! It was calculated than ignored.
   This meant that anything pasy hue 255 was never used! Now we have purples.
* Only expand the u8 up to 359* (not 360). 360 exactly seems to cause a math
   problem I'm not interested in fixing.
