The scale gesture detector has a new behavior to make onScale callbacks during swipe after a double tap. The screen magnification is triggered after a trippe tap so if the user trippe taps and holds to do a temporary magnification and tries to change the zoom level with another finger, erroneous results are obtained. The ScaleGestureDetector uses an APIs level check for the new behavior but the ScreenMagnifier is a platform feature. We now explicitly ask for the old behavior. bug:11033376 Change-Id: I0dfb14dd3abcaa34ad1f40447c631b4203797378
