Added workaround for window.scrollX compat.
window.scrollX/Y is not available in IE11. As far as specifications go, is currently only specified in draft (http://dev.w3.org/csswg/cssom-view/#refsCSSOM). Falling back to
window.pageXOffset seems like a good workaround.
On a related note; my Emscriptified project runs on IE11 although performance is very poor (mostly due to Internet Explorer itself, I think). It's pretty finicky about the shaders, as they introduced an extra set of requirements. (inout/in/out keywords not supported, can't construct mat3 from mat4, etc).
