Huh.  I though we had that already.

Nobody will remember the order and meaning of the options.  One could
use named arguments, but since you are providing a "text" anyway, I'd
make that non-optional and leave everything else away.  As text can be a
markup, it can call upon font-family and/or font-name itself as
required.

Depending on how much preformatting you want to provide, you can accept
a markup list instead of a single markup and create a center-column (or
whatever else) from it.
