Detailed Description

A container of widgets for selecting font faces.

It is used by the TextEdit and Glyphs panel dialogs. The FontSelector class utilizes the FontLister class to obtain a list of font-families and their associated styles for fonts either on the system or in the document. The FontLister class is also used by the Text toolbar. Fonts are kept track of by their "fontspecs" which are the same as the strings that Pango generates.

The main functions are: Create the font-selector widget. Update the child widgets 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). Emit a signal when any change is made to a child widget.
