[vtk-developers] [EXTERNAL] RGBToHSV hue range

[Moreland, Kenneth]

I'm all for clarifying the documentation (thanks for volunteering, David),
but I recommend NOT changing the implementation for two reasons.  First,
scaling between 0 and 1 (or 0 and 255 for fixed point) is pretty common.
Second, this would be a disruptive change with no smooth transition path.
