The way it used to work was a bit nonidiomatic but the replacment
is idiomatic way of iterating used elsewhere.
The new code just doesn't check nullability of "characters", which isn't
what we do anywhere else.
All the other similar iterating API are like this and don't have such
comment, written at the time I wasn't familiar enough with the way such
API are shaped.
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.
This was done in #770 but no indication of anyone is using it,
let's remove it from our meson port and we can just don't care about
it in autotools port after the migration to meson.
Instead of passing dependencies as required we used one giant shared
dependency list containing all dependencies for every library/executable.
While this kinda works, the specified deps are also used for generating
the pkg-config files and this leads to lots of Requires.private and Libs.private
entries which aren't really needed.
This removes the "deps" array and replaces it with a few smaller ones and
makes sure the public libraries only get passed the dependencies actually
needed.

ptem, used for AAT's tracking/`trak` table is equivalent to opsz of variable fonts.
For variable AAT fonts, such as SFNS, ideally variable axis of the hb_font_t
should be set and equivalent to ptem, https://crbug.com/1005969#c37
Searches variation axes of a hb_font_t object for a specific axis first,
if not set, then tries to get default style values from different
tables of the font.
So one can run a category of interested tests like
meson test -Cbuild --suite aots --suite src --print-errorlogs
Intead issuing particular tests which also is possible like
meson test -Cbuild test-shape --print-errorlogs
This way it won't ruin incremental builds.
We need a better way to declare source altering tasks
https://github.com/mesonbuild/meson/issues/7156
yet this is good enough despite being not idiomatic.
It is however not that smooth yet as the change may is detected on the
next meson run. One of course can issue ./gen-ragel-artifacts.py
manually for better experience before running meson.
Using a C linker was limited to non-Windows as 20a840c7, let's
revisit this while transition to meson.
Packagers easily override that via the option and use a C++ linker
if needed.

AAT::Lookup has no other way to detect whether it is returned from
a real and sanitized font data or from a null pool, this checks if
the table has been recognized valid by sanitizer by checking
table's major version which is zero if returned from a null pool and
non-zero if is from a sanitized font data, it is expected the other
calls of the table (unlikely to have more calls however) also do a
similar version check before calling the lookups used on the table.
In case a user passed -Dintrospection=enabled the build would just ignore
it by default because gobject defaults to disabled and the introspection build
gets skipped.
Instead, if introspection is explicitly enabled but gobject is for some reason
missing error out.
