Test cases:
Old versions (v11): http://www.silicongraffiti.com/Wheels/index.html
Touch on IE doesn't work, but scrolling is smooth in all browsers. New versions (v12): http://www.silicongraffiti.com/Wheels/index_v2.html Touch works on IE, scrolling works on everything except IE - IE ignores the first, third, fifth, etc. events.
