Touch problems with Internet Explorer 11 (seen on Windows 8.1 RTM) and Leaflet

[Ernie23]

Have some touch problems when i open a website with Leaflet in the new Internet Explorer 11. Zoom, Pinch to zoom and other touch gestures does not work. After that the Leaflet control is unresponsive. I got this issue on several tablets / touch devices with Windows 8.1 (RTM) and IE11. It seems that the IE11 uses pointerevents instead of ms-pointerevents.

I found this on http://msdn.microsoft.com/en-us/library/ie/hh772103(v=vs.85).aspx

@danzel Dave, you're the one to save the day here :)

[danzel]

oh wow.... thats um a great change microsoft....
Will try do a fix next week, going to need some remote testing as I don't have 8.1 access.

We could also try doing a blind fix in a separate branch (if it's really a prefix issue) and ask@Ernie23 to test :)

Hi, i fixed the issue with pointer based devices in leaflet.

It's testet on our Surface Pro with win 8.0 and 8.1, our IPad and all other common desktop browsers.

Where can I upload or post these changes?

@danzel hey Dave, did you look at this too?

[danzel]

#2039 is the related PR.
We need to do something like that but less of a mess. Will take a look later this week.

Lets aim for a stable release with a fix before IE11 massively goes live. :)

[danzel]

gonna take a crack at it today

[danzel]

Looks like chrome will eventually use pointer events rather than touch as it does now

@Ernie23 @DanielX2 can you confirm the pull request above fixes it on mobile tablets with IE11?
