(Caveat: I haven't really been following this thread.
Apologies if I misunderstand the intention or the
scope, e.g., if this is off topic.)

I guess y'all are trying to come up with the ability
to have vertical display lines similar to window
dividers - maybe 1-pixel wide (or configurable as
N pixels wide?).

Keith is apparently working on such a thing for a
fake-cursors implementation.  And this thread is
about using such a thing for indicating the fill

Do I understand that right?  If so, will the approach
to doing this be general, so the same implementation
(in C) can be used for both of these applications?

In that case, could it also be used also for vertical
lines separating table cells and other things.

If so (if we'll have a general feature for such
support) will there be something similar for
horizontal lines?  And will we be able to limit
such lines (start and stop positions), or will
they always be across an entire window?
