How to work with stylus functions in air 3.3 sdk?

Hi guys, I really need to know if it is possible to create an app that use the stylus for drawing and have acces to functions like pressure recognition and stylus buttons press.

In AIR 3.3 sdk, they said that Stylus support for Android 4.0 is available: http://forums.adobe.com/message/431700, but I don't find anything related to stylus in the language reference docs or any other resource that can guide me to implement these functions...
