Can we just store this natively and have Java just always delegate to native
when we have to talk to the BlimpContents?  The only times I can see this
happening for now are onSizeChanged() and onTouchEvent(), both of which will
marshal to native here and will hit the BlimpContents in native only.

Wow, that had a lot of nice consequences!
