Magnification center moved to the screen center

In
android.accessibilityservice.cts.AccessibilityGestureDispatchTest#testClickWhenMagnified_matchesActualTouch
magnification center was moved to the screen center. Previously
magnification was align so that top left corner was mapped to itself.
It worked fine on rectangular screens, but was failing on round screens
as top left point with its surroundings was off screen.
