 *
 *  1. Header (offsets to other sections)
 *  2. Global font information
 *  3. Character metrics
 *  4. Pair Kerning data
 *  5. Comment, Notice, etc. strings
 *  6. Font metrics structure
 *
 *
 * 1. Header
 * ---------
 * Offset  Type
 *   0000  word    Version from StartFontMetrics
 *                 (whole portion in high byte, fractional in low)
 *   0002  word    Offset to Global font information
 *   0004  word    Offset to Character metrics
 *   0006  word    Offset to Pair Kerning data
 *   0008  word    Offset to Strings section
 *   000A  word    Offset to font metrics structure
 *   000C  word    Size of the 5 above sections (global, metrics, etc.)
 *
 * Note:  All sections (char metrics, kerning, etc) start on
 *        word-alinged boundaries.
 *
 *
 *
 * 2. Global font information
 * --------------------------
 * Offset  Type
 *   0000  word    VariablePitch       (ie, 1 for true, 0 for false)
 *   0002  word*4  FontBBox
 *   000A  word    CapHeight
 *
 *
 *
 * 3. Character metrics
 * --------------------
 * Offset  Type
 *   0000  byte    Char code to output in a PostScript show command
 *                 in order to display this character.  0=the font
 *                 must be remapped in order to display this char,
 *                 in which case just output the char directly.
 *   0001  word    Character width ("WX" argument)
 *    ......
 *
 *
 *
 * 4. Pair Kerning Data
 * --------------------
 * Offset  Type
 *   0000  word    Char code 1
 *   0002  word    Char code 2
 *   0004  word*2  Kerning vector         ("KP/KPX" arguments)
 *    .....
 *   NOTE:  If this font is codepage 850 (winthorn multi-codepage support)
 *          then the character codes above are actually the codes as
 *          remapped by the codepage vector -- presently in the range
 *          of 1-316.
 *
 *
 *
 * 5. Comment, Notice, Version, Fontname, EncodingString, and Weight strings
 * -------------------------------------------------------------------------
