​That's a good idea to use an existing resource. I've added this to our
ticket.

​We sort of have this already with the ".hluresfile". However, with
something like a font height, this usually gets controlled by the "plot
manager", which is trying to manage all elements of a plot if you resize
it.

We have a separate ticket just for font heights alone (NCL-194), because
we've had many people ask how they can set a fixed font size regardless of
the size of everything else.  I've added your comments to this ticket which
will help "elevate" it.  I agree that we need something that allows you to
"fix" the font size for all plot elements.
