adjusting rounding in getElementPosition

[thenewguy]

Moved from #243 (comment)

I am observing an odd issue that I couldn't reproduce it at first... if you open the page at 100% zoom it works as expected. If you change the zoom to 110% it alternates between scrolling to y coord of 429px and 430px. This was observed at a window width between 548px and 637px according to the chrome web developer plugin. Is the use of parseInt in getElementPosition important?

Changing it to the following prevents the pixel jumping I am observing:

        function getElementPosition(target){
            var iFramePosition = target.getBoundingClientRect();

            getPagePosition(iframeId);

            return {
                x: Math.floor( Number(iFramePosition.left) + Number(pagePosition.x) ),
                y: Math.floor( Number(iFramePosition.top)  + Number(pagePosition.y) )
            };
        }

The modified getElementPosition function is demonstrated here: http://thenewguy.github.io/iframe-resizer/issues/243/6/host.html

Do you want to put that in a pull request?

I am doing that now

Not sure how important identical whitespace is to you... eclipse is being difficult with it today

Tabs rather than spaces.
