[ft] Parsing AFM files without PFA/PFB

[Antony Lee]

Hi all,
Does FreeType provide a way to parse an AFM file and extract the
corresponding glyph metrics and kerning information, when the accompanying
PFA/PFB file is not present?
One use case is Matplotlib's postscript backend, which can layout glyphs
just based on their metrics but does not need the pfa/pfb files itself.
Right now Matplotlib uses its own handwritten AFM parser, but it would be
nice if FreeType's AFM support could be used instead.
Thanks in advance,
Antony Lee
