iOS 6.1.2 input range sliders not working

[tkzic]

On my iPad, none of the range sliders (like oscillator frequency) are working. After some poking around, I found that html5 range sliders would not work if added anywhere on the page.

Tracked it down to "pointerevents.js" - disabling that file allowed range sliders to work again - but it also breaks all the event handling code.

Looks like the version of pointerevents.js in repo is modified from original and minified too - so this is where I take a break...
