Mobile/Archive/Touch Events

Summary

Implement events that allow web pages to capture touch and multi-touch .

Current Status

• Gecko currently implements MozTouch* events on Windows 7 only. Work-in-progress patch in bug 603008 to use these events in Android chrome.
• Working with [W3C http://www.w3.org/2010/webevents/ Web Events WG] on new spec (currently in Editor's Draft), based on WebKit touch events (different from MozTouch* events).

Next Steps

• Working prototype implementation (finish WIP in bug 544614).
• Move toward W3C Web Events spec.
• Decide on "escape hatch" UI (e.g., bug 441590 - border around edge of screen that can still be used for panning in menus). Still needed on Android?
