Behdad Esfahbod b2a1acccd9 Simplify get_glyph_alternates() dispatcher
Trying to make it **very simple** to add a specialized dispatcher for
one API to be routed to just a few objects (one in this case).
2020-06-18 16:41:31 -07:00
Behdad Esfahbod ffe8d3f39d Use dispatch for get_glyph_alternates_t
First time we do this in a way that if target object doesn't have the matching
function we basically "ignore".  Risky but I feel like is the right decision
for this case.

I'm going to put back the template varargs and use those, which would make
the dispatcher be just that: "dispatcher", and wouldn't need to carry the
call context.  That would be a refreshing change I think.
