Hi,

thank you for the reply.

This makes sense. If you can cache the results, the interpreter has a fixed, 
one-time cost. Are these glyphs stored on the disk?

Are these programs provided by the font file itself or comes from another 
source?

Perhaps multithreading can help more here than JIT. I suspect hinting can be 
done parallelly.
