  /**
   * 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.
