Settings for the screen magnification feature.
1. Screen magnification on the device has to he explicitly enabled
by the user before allowing a global gesture related interactions.
The feature toggle setting is in Settings->Accessibility and it
is a separate screen with instructions how to use the feature
and a toggle switch.
2. Added a setting in developer options for toggling the magnification
auto update feature. If this features is on the screen is zoomed
out or rotation or activity start. Also if the feature is enabled
the magnified viewport will scroll to show popped up windows.
