IE8 falls into infinit loop in getViewportWidthInCssPixels()

[tokkonopapa]

In IE8, the variable widths looks like [null, 600, 800, 600] and will be [600, 800, 600] by widths.splice(i, 1);. But the variable l is still 4. So i will refer to the out of range.

The below code can fix this issue.

function getViewportWidthInCssPixels() {
...
    for (; i < l; i++) {
        // If not a number remove it
        if (isNaN(widths[i])) {
            widths.splice(i, 1);
            i--;
            l--; // need decrement
        }
    }
...
}

Thank you for spotting that bug. It's already fixed in 1.5.3. Could you give it a try?

I tested 1.5.3 using IE8 and found everything is fine! Thanks for quick update!!
