-/** This class manages a font.
-The idea is to create a FontInfo object with a font name pattern with a
-wildcard at the size field. Then this object can host request for font-
-instances of any given size. If no exact match is found, the closest size
-is chosen instead. If the font is scalable, the flag lyxrc->use_scalable_fonts
-determines whether to allow scalable fonts to give an exact match. */
