Add hb_font_funcs setter functions
Make hb_font_funcs_set_* accessible from the JavaScript side, with HB being able to call JavaScript functions the user passed in.
Had a quick look at this, but failed to understand the emscripten docs and various StackOverflow answers...
We will need this, too, at some point. Specifically these:
-
hb_font_funcs_set_nominal_glyph_func -
hb_font_funcs_set_glyph_h_advance_func -
hb_font_funcs_set_glyph_v_advance_func -
hb_font_funcs_set_glyph_v_origin_func
I am brand new to this project (although I have used and contributed to the equivalent parts of uharfbuzz), and hope to find my way so I can contribute.
In the meantime, some guidance about how to approach this would be very welcome.
You can see an example of setting drawfuncs here: https://github.com/aliftype/rana-kufi/blob/99f9ba560e3c4a6d858d2b9d2c807466fb975c49/docs/app/HarfBuzz.js#L116
