   \class FontDatabase fontdatabase.h
   \brief The FontDatabase class provides information about available fonts.
 
   Most often you will simply want to query the database for the
   available font families().
 
   Use FontDatabase rather than QFontDatabase when you may need access
   to fonts that are not normally available. For example, if the
   freetype library and the Qtopia freetype plugin are installed,
   TrueType fonts will be available to your application. Font renderer
   plugins have greater resource requirements than system fonts so they
   should be used only when necessary. You can force the loading of
   font renderer plugins with loadRenderers().
