I like your idea that this would all be defined in one place.

One nit is that the variable name there is mouse-wheel-scroll-amount,
and I'm not sure this is the best name for functionality to change the
font size.  If we go ahead with that, perhaps it should be renamed to
something like mouse-wheel-scroll-modifiers?
