right- but what is the frontend going to do with that, read the user's
setting, then turn the data back around and set the resolution and
duplex options? it seems that would be better done in the backend
itself.

i see no point in this, however, it does point to an interesting
problem. all these buttons are now semantically named, so you wont be
able to have one called 'resolution', since you already have an option
with that name. should we prefix these with 'button-' or some such?
