/**
* Hacky fix for Issue #4 and
* http://code.google.com/p/android/issues/detail?id=18990
* <p>
* ScaleGestureDetector seems to mess up the touch events, which means that
* ViewGroups which make use of onInterceptTouchEvent throw a lot of
* IllegalArgumentException: pointerIndex out of range.
* <p>
* There's not much I can do in my code for now, but we can mask the result by
* just catching the problem and ignoring it.
