Sliders that go negative have unreachable values

Which OS/platform are you using? A Macosx/64 user reported this to me directly but I couldn't repro myself.

It seems like if you split the slider into 1/4ths, the 3rd quarter is the section that is skipped.

I've seen this both on my MacBook Pro and primary desktop system which
runs Linux most of the time.

Mac is on OSX 10.9.4 and I have my own gcc toolchain which is on version
4.8.2.

Linux is running Linux Mint 17:

OK I am on my Mac now and it repro!

Fixed!
I was calling abs() which for some reason resolved to abs(float) on the architectures I was using (Windows & PS4) but abs(int) on Mac/Linux. It was also breaking the RGB<>HSV conversion.
