Stock touch sensitive Silverlight 4/Windows 7 Mobile Image display control

i've seen this question: SO - W7M gesture events but my requirements slightly different. Has anyone encountered a gesture aware image viewer control that supports pinch/squeeze/scroll? The SL4 toolkit add-ons are a partial win but do not take it far enough. If neccessary I can code all from 开发者_如何学Cscratch but would prefer not to duplicate effort at this point.

Thx++

There's a pretty great implementation of pinch zoom that I encountered when I asked a similar question.
