Description

Testing this in revision 462741, I have created a font file with only two glyphs
A and V, and set kerning between them.

The XML metrics file (excerpt below) shows that the indexes in <kerning> are
glyph indexes, but AFAICS the layout code expects unicode indexes. I'll change
that in the TTFFile font decoder class, to have unicode indexes in the <kerning>
section.

<multibyte-extras>
<cid-type>CIDFontType2</cid-type>
<default-width>0</default-width>
<bfranges>
<!-- mapping of glyph indexes to unicode -->
<bf gi="0" ue="0" us="0"/>
<bf gi="3" ue="65" us="65"/>
<bf gi="4" ue="86" us="86"/>
<bf gi="0" ue="65535" us="65535"/>
</bfranges>
<cid-widths start-index="0">
<wx w="684"/>
<wx w="1000"/>
<wx w="1000"/>
<wx w="684"/>
<wx w="684"/>
</cid-widths>
</multibyte-extras>
<!-- glyph index 3 is A in my font, 4 is V -->
<kerning kpx1="3">
<pair kern="-279" kpx2="4"/>
</kerning>
