* Create the font-selector toolbar widget.
* Update the lists when a new text selection is made.
* Update the Style list when a new font-family is selected, highlighting the
* best match to the original font style (as not all fonts have the same style options).
* Update the on-screen text.
* Provide the currently selected values.
