I try to zoom with mousewheel on a Raphael paper using viewBox. Here is the JSFiddle code.

it works but now i want to zoom in the center and i have no idea where to start. I guess i should change the viewBox x and y coordinates. I have tried this (in the function handle(delta)):

x = paper.width - viewBoxWidth;
y = paper.height - viewBoxHeight;
paper.setViewBox(x,y,viewBoxWidth,viewBoxHeight);

but didnt work. I would appreciate any help. Thank you!
