// NOTICE ****** IMPORTANT  :
// for proportional string:
//  1. You must add the following struct into menudef.h
//	typedef struct
//	{ BYTE SpaceWidth;
//	  WORD LineData[18];
//	} PropFontType;
//	typedef WORD PropFontType;
//     If you use compressed proportional font, then change PropFontType as
//       typedef WORD PropFontType;
//  2. declare font table as
//	extern PropFontType code tPropFontSet[]; // for common font
//	extern PropFontType code tPropFontSet1[]; // for 1st additional font table
//	extern PropFontType code tPropFontSet2[]; // for 2nd additional font
//     if you adopt compressed proportional font, you must declare additional three mapping table
//      extern WORD code tPropFontMap[];
//      extern WORD code tPropFontMap1[];
//      extern WORD code tPropFontMap2[];
//     the content was from font editor
//  3. add external declaration
//       extern BYTE SecondTblAddr; // for refer common font table or 1st/2nd font table
//       extern BYTE LanguageIndex; // for refer 1st font table or 2nd font table
//         _BIT6..7 of LanguageIndex was used for specify how many pixel width among proportional string
//                 The value range is from 1 to 3. the value 0 will be specify as 2
//	Ex 0xC0 indicate pixel width is 3.
