elisabets@: Is there a particular bug/issue associated with this addition? Or
would this be wired up to an explicit  UX/functionality-related signal?

We need it because we want to scroll to the edge of the view when a fling
velocity is above a certain threshold, and if you need to do some scrolling
during a fling, we'll need to cancel that fling before anything else (otherwise
we will end up with the wrong state of things).

If you feel like it's excessive we can keep it as a patch :)

I think it's a fine addition, just wanted to understand the use-case.  So you
listen to fling gesture ack's using the GestureStateListener, and if one is of
sufficient velocity you manually cancel the fling and take over scrolling?

Let's move the method here, and add a brief Javadoc explaining what it does
(even though it sounds self explanatory =/), thanks.

Oops, sorry I missed that you had updated the patch (reviewers don't get
notifications when you upload a new patchset, only when you have comments and
"Publish + Mail Comments"). lgtm.
