Might the suggestion that FreeType could perhaps /parse and expose/ all tables
without necessarily /handling/ all of them, help in this discussion? 

Analogous to Adam's audio/video example, could it make sense for FreeType to
implement the audio/video container demuxers (table parsers) and the video
codecs (glyph rendering), but not the audio codecs (text layout)?

(Aside, I don't hear anyone mentioning m17nlib for text layout these days, even
though it aims to handle all aspects of all current unicode scripts. I've also
found its API for that quite nice and elegant. Weird is that I see it most
often in the context of multilingual input alone. Does it have pronounced
disadvantages compared to Harfbuzz or Pango that I'm missing?)

Kind regards,


Emile.

Not sure if you were inviting comments from interested bystanders too, but I do 
think that the 'warp off' image has more consistent visual density. 

The weight from glyph to glyph seems to have more variation with warping on. 
It's hard to put this down to specific details of individual letters; it's more 
of an overall impression.

Does that make sense at all?

Kind regards,


Emile van Bergen.
