[wip] Mobile touch events

[edenh]

Previously #749.

A work in progress, resolves #657. Rendering is pretty funny though #750.

• panning
• pinch zoom
• pinch rotate
• panning while pinch-zooming
• double tap
• add tests for updated easeTo

Looking forward to this functionality. Thanks for doing this!

I gave this a try on my single page app, it works really well apart from one problem I seemed to be having.
The map I was using it on covered the whole page, but when I called map.remove(), I couldn't scroll on any other page on my app even though the map was no longer visible and the map DOM element had been removed. Maybe the touch events aren't being unregistered?

Might be worth ensuring that how the map responds to touch gestures matches what’s been implemented in Mapbox GL for iOS and Android (mapbox/mapbox-gl-native#1292, mapbox/mapbox-gl-native#553).

What's the status of touch for the web version?
I don't get any touch response in Chrome on Sony Z3 or HTC One M8 for example :(

[tmcw]

why not use undefined here instead of having add the null check on the other side?

[jfirebaugh]

#1215 removes the need for null or undefined positional arguments.

Hey guys,

Thanks for this! I am able to use mapbox-gl-js on my android phone now because of your great work!

I merged the latest master branch into the touch branch, and only had to change a couple of things afterwards to make it work again (at least on my Samsung Galaxy Mini S4)

I have published it here: https://github.com/trappsnl/mapbox-gl-js/tree/touch

Not sure if I should make a new pull request now? or I guess @edenh can merge my changes into this one?

Anyways, I'll try to help as much as I can for Android support, and have some more devices where I will test this on.

+1 for this. I'm using https://mapbox.s3.amazonaws.com/mapbox-gl-js/master/mapbox-gl-dev.js but touch events still not working (iPhone 5s with iOS 8, Safari, Chrome).

I'll look into finishing and merging this early next week.
@vespakoen thanks for the help!

[mourner]

Currently broken because of #1268

[mourner]

Will handle subsequent improvements in further commits.

👍 Awesome!! Thanks a lot!
