Rotation moved the centerpoint slightly #2

On FireFox, when I rotate the shapes after a scale transform the center get shifted slightly (sometimes by a larger amount). This seems to work for all shapes. To duplicate, pick demo 4 and change the horizontal scale and then rotate - the center will now have shifted slightly so the shape wobbles instead of rotates symetrically. I didn't get to investigate but maybe a rounding error creeps in?

Sorry, I'm not sure what you mean by "change the horizontal scale" in demo 4? There aren't any tools to do that in demo 4? Or do you mean by resizing the browser window? In any case I can't make the shape wobble. Please could you clarify? Thank you for the report. Andy
