  	This header-file contains the declarations of all low-level font-related classes. 
	Their parent classes are in the parentheses:

		class FKerningRec;
		class FDTDefineFont; (public FDT)
		class FDTDefineFont2; (public FDT)
		class FDTDefineFontInfo; (public FDT)
//		class FGlyphEntry;

  	Note: Class FGlyphEntry has been commented out. Need to fix.
