(More on the tracking bug)

Multitouch API front

• bug 508906 [Win7] bug 544614 Fennec

- At the moment, experimental patch for Windows 7 present on Bug 508906.

- Stuck in two issues:

• Waiting for a real (draft) spec to be published
• Thinking on how to deal with Windows 7 limitation that we cannot get gestures and raw data at the same time

Plan

• Get our implementation close to a possible spec
• Work on switching modes on Win7 when a webpage request any event from the API
• Deliver the raw input API first
• Get around windows gesture limitation or implement our own gesture recgonition to complete the API
