// Note:  This is *not* a foolproof method for finding the name of a font file.
//        If a font has been installed in a normal manner, and if it is in
//        the Windows "Font" directory, then this method will probably work.
//        It will probably work for most screen fonts and TrueType fonts.
//        However, this method might not work for fonts that are created 
//        or installed dynamically, or that are specific to a particular
//        device, or that are not installed into the font directory.
