Unmatched bipolar sliderpacks broken

[d.healey]

Bipolar slider packs with unmatched min/max values don't work.

For example min: -1, max: 10

If the min/max are equal, like -1/+1 then it works.

@d-healey I found the issue and currently working the math... Should the zero point be centred or offset depending on the min max difference?
I mean in the case -1/+10 do you prefer the 0 to be at height/2 or 10*height/11?

[d.healey]

@ustk I think having it in the centre is easier to see, but I don't mind really.

@d-healey Got it to work with asymmetric values but not identical pairs anymore
But getting close...

@d-healey That's pushed
