Remove ClassDef->Defined field. This is the comment accompanying it:
The `Defined' field is not defined in the OpenType specification
but apparently needed for processing fonts like trado.ttf: This
font refers to a class which contains not a single element. We
map such classes to class 0.
The comment is correct that trado.ttf (MS Traditional Arabic) uses
such classes. However, in my testing I couldn't identify any
problems with the font if the special handling is removed. I also
processed as many fonts as I could get my hand on and trado.ttf was
the only not-totally-broken font hitting the special-case code.
DejaVu fonts hit it too, but I'm sure they do not require the
special-handling code. Most probably, that code introduces bugs
in them.
The special-casing was consuming lots of memory. EIGHT MEGABYTES
for loading DejaVu Sans! While this could be complete fixed, I
decided to remove the special-handling code altogether. I don't
think it will make any real difference, and if it does, we'll fix
fonts. Such hacks will not be in harfbuzz-ng anyway.
Bug originally reported by nsf.
