Avoid overflow in focus fudge calculation

When comparing decoding the next View to get focus, the last-resort
calculation (magic number and square of distance between the View
corners) could overflow, giving a false positive. This causes the
focus to jump around in certain cases. Change from int to long to
avoid in the foreseeable future.
