How do I fix the sprite size when has some rotation?

For the 2D tool i'm doing you can pick a point in the sprite and drag it to resize it.

The behaviour on resizing works.... but only when the sprite not have rotation. In that moment all brokes.

I tried more expresions, some ones works but then i can't resize on negative values(using distance). So i need the resize behaviour like now on scalers but that works also with any sprite rotation but after various can't get it :S .

For drag i'm using the Drag&Drop2 behaviour by Rexrainbox:
