I understand that.  When I say "intangible" I just mean that the
cursor will be somehow moved outside of the area.  When I mean intangibility
as is implemented by the `intangible' property, I say it explicitly.

I intend to provide the "invisible is intangible" by extending
the point adjustment function, as in my previous patch.
