I forked otf2bdf for meeting my own needs as well. Changes:
* add `-A' switch for no-autohint
* add `-a' switch for force autohint
* add `-B' switch for no embedded bitmap
* add `-g x' switch for selecting hinting algorithm (x=0-4)
* Commented out Determine the actual bounding box of the glyph bitmap part, instead, use FT_Glyph_Get_CBox()
* Extends dump area to whole valid Unicode codepoints (U+10FFFF)
