[Magnifier-37] Hide handle when overlaps magnifier

In most cases, the magnifier will be displayed above the current line,
so it will not overlap with the handle being dragged. However, when
there is not enough space in the current surface for the magnifier to be
displayed above the current line, the handle can overlap with the
magnifier. Since the handle is implemented as a different window, we
cannot really control the z ordering between them, and we noticed that
the handle will be rendered over the magnifier, which looks bad. This CL
better handles this situation, by hiding the handle when it would
overlap with the magnifier.
