+ *
+ * The main functions are:
+ *   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.
