Description of font header
============================
There are 13 parameters in the font header (first record)
Some of these are simply placeholders; others will vary
with the size of the font.

Par #1   Font type
   0 = 7-bit   (chars 32 to 127)
   1 = 8-bit   (chars 32 to 127 and 160 to 255)
   Value is always 1.

Par #2   Baseline position
   All fonts must have a baseline.  The baseline
   position is defined as the number of dots in
   the font cell above the baseline.  The fourth
   glyph parameter specifies the top offset of
   of the glyph relative to the baseline.  This
   is also measured in dots.  At the time of
   printing, font baseline will line up with
   the vertical position of the cursor.
   Value will depend on size and type of font.

Par #3   Cell Width
   Value = width of widest glyph in font

Par #4   Cell Height
   Value = Baseline position + 1 + maximum number
           of dots below baseline (for lowest reaching
           glyph in font).

Par #5   Orientation
   0 = portrait
   1 = landscape
   Value is always 0.

Par #6   Fixed vs. Proportional
   0 = fixed
   1 = proportional
   Value depends on font.

Par #7   Symbol Set
   Value is always 277

Par #8   Pitch
   Value is 4 times the horizontal width of the
   font.  Think of it as 4 times the width of
   the space character.

Par #9   Height
   Value is 4 times the height of the font cell.

Par #10  Style
   0 = upright
   1 = italic
   Value depends on font.

Par #11  Stroke weight
   Value may range from -7 to 7, with 0 being normal

Par #12  Typeface
   Value usually 3 = courier

Par #13  Thinning parameter
   0 = do not thin
   1 = thin the font before loading to printer
   Value depends on font, heavier music fonts should
     be thinned.

Parameters such as Height, Style, Stroke weight,
  Typeface and Symbol set are used in the LaserJet
  font selection process, and normally will not
  be of concern to our applications.
