pointer array is GlyphClassDef->cd.cd2.ClassRangeCount+1; the nth
array then contains the glyph class values of the glyphs not covered
by the ClassRangeRecords structures with index n-1 and n. We store
glyph class values for four glyphs in a single array element.
`LastGlyph' is identical to the number of glyphs minus one in the
font; we need it only if `NewGlyphClasses' is not NULL (to have an
upper bound for the last array).
Note that we first store the file offset to the `MarkAttachClassDef'
field (which has been introduced in OpenType 1.2) -- since the
`Version' field value hasn't been increased to indicate that we have
one more field for some obscure reason, we must parse the GSUB table
to find out whether class values refer to this table. Only then we
can finally load the MarkAttachClassDef structure if necessary. */
