/**
 * Hacky fix for Issue #4 and http://code.google.com/p/android/issues/detail?id=18990
 * 
 * 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.
 * 
 * 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.
