getScale() and getCenter() doesn't work using doubleTapZoom

[dandys71]

Expected behaviour

To get actutal state using getScale() and getCenter() after using doubleTapZoom as it works when using standard two finger scaling.

Actual behaviour

Return bad values. It only returns values of two finger scaling. The change isn't reflected in the attributes, it does not change scale and center attributes after using doubleTapZoom.

Do I have to use different functions to get actual state after double tap zoom or is nessacery to edit SubScalingImageView.class? And how?
