Agreed.  I'm thinking maybe a pair of functions for each component,
set-*() and adjust-*(), for either overriding the given channel or
adjusting it up or down.  Hmm, though, there's argument for both
adjusting by a set amount, and by a percentage amount, at least for
some channels.  I'll look into what the preprocessors do, precisely.
