OTF generation bug?

George,

convert Ghostscript's c059016l.pfb with the attached script to an OTF
file:

  fontforge -script pfx2ttf.fontforge c059016l.pfb c059016l.afm c059016l.otf

Checking with FreeType's ftview, all advance width values are far too
big.

The reason for this seems to be that you set the `defaultWidthX' field
in the private dictionary (771 for the above font) without adjusting
the charstring widths.  For the `space' glyph in the above font, the
charstring width is 287 (this is the right advance width value, BTW),
giving an advance width of 771+287=1058 units, which is wrong.

   Cut();

elseif ( err < 0 )
   Print("An error occurred while searching for the \"numero\" glyph");
endif

Generate($3 + $fontname + ".otf");
