Support circular magnification frame on circular devices
The magnification viewport expects its boundary to be a rectangular region,
and always draws it as such. This change causes the indicator to draw as a
circle on devices with circular displays. This also refactors the width of
the indicator's frame to use a proper dimension resource and updates the
width to 4dip.
