The Max. Width control contains a value that specifies the width of the
widest character in a font. For fixed-pitch fonts, this value will always
be equivalent to the value specified in the Average Width control. For
proportionally spaced fonts, UniTool will calculate and insert this value
in the control (using values from the character-width table).
