Broken layout in IE11

[d13r]

In IE11 the popup is not positioned correctly:

I tracked it down to window.scrollX/Y in viewportDetails() - these are null in IE11. That causes roomCalc() to return NaN for all values.

I fixed it by replacing that function in bigfoot.js with this, which uses jQuery to get the values:

      viewportDetails = function() {
        var $window = $(window);

        return {
          width: window.innerWidth,
          height: window.innerHeight,
          scrollX: $window.scrollLeft(),
          scrollY: $window.scrollTop()
        };
      };
