closes #6528
There were two issues with center based scaling from one side only.
First of all we did not define an opposite origin for the center origin, resulting in a swapped origin undefined and wrapWithFIxedAnchor returning NaN coordinates.
On top of that, human mouse movements on a centered originated scaling from a side only, would often cross the origin point, creating a flip of the scale, and producing, once the NaN problem was fixed, potentially unwanted coordinates flips.
