// The array has wGlyphCount elements and each element is the char width 
// for a single glyph. The first width corresponds to glyph index wStartGlyph 
// and so on. The byte offset is relative to the beginning of WIDTHTABLE
// structure and must be WORD-aligned.
// In case of Western device font, proportional font has all varibal pitch
// characters. This means that dwRunNum is set to 1 and loCharWidthOffset
// would be an offset from the top of WIDTHTABLE to a width vector of all 
// characters.
// In case of Far Eastern device font, basically IFIMETRICS.fwdAveCharWidth and
// IFIMETRICS.fwdMaxCharWidth are used for single byte and double byte character
// width. If a font is proportional, a UFM has a WIDTHTABLE which represents
// only the proportional pitch characters. Other characters use fdwAveCharWidth
// and fwdMaxCharInc for single and double byte characters.
