Of more interest to us is how they describe each character.
The ENCODING gives the index, in decimal, of the character within
the character set. 36 is the value of the dollar character in
the standard ASCII set. The BBX field is the bounding box of
the character. So this character is 3 characters wide, by seven
tall. The next two numbers are the offset of this character.
There is no horizontal offset, but the character should be drawn
one pixel below the baseline. This allows the S of the dollar
to sit on the baseline with the vertical stroke dipping slightly
below it.
The bitmap then consists of seven hex values. Only the first
three bits of each hex value will ever be used since the width
is three. The drawing of the character shows the pixels corresponding
to each line of the array.
