Current work:
- Windows metro: Finish Pointer Events / touch-action as reference implementation for W3C spec (MS Open Tech).
- Windows desktop: Fix and enable Touch Events, and implement Pointer Events / touch-action (MS Open Tech, Platform Integration?).
- Firefox OS: Implement and enable pointer events / touch-action (MS Open Tech?).
Possible future priorities:
- Android: Unify Android and Gecko APZC and viewport code.
- Android: Implement Pointer Events / touch-action.
- Mac: Implement async pan/zoom for trackpad gestures.
- Windows desktop: Implement async pan/zoom for touch-screen and trackpad gestures.
- Platform: Implement CSS Device Adaptation to rationalize mobile viewport code (bug 747754).
