wm: Display borders when hovering over resize handles.
This makes us display a translucent black box when the
pointer is over a border that can dragged to resize a
browser window.
Ideally, we'd do something similar for panels as well, and
we'd fade to a nicer-looking, heavier shadow instead of just
drawing a translucent box. This doesn't look too terrible
to me, though, and gives us a way to see how this feels.
