- Add TouchEvent and TouchEventPoint messages to the input event protocol. - Extend the InputStub interface with an InjectTouchEvent() method. - Update InputEventTracker to track touch points, and to cancel them when ReleaseAll() is called. - Implement touch handling in the client plugin, but off by default. The web-app may choose to enable touch handling if desired. - Add a TouchInputScaler that scales and clamps touch points, similarly to the MouseInputFilter, for use by both client and host.
