This is sufficient to resolve a few ttx table diffs on fontc_crater, but needs refinement.
This is heavily WIP; it needs a tidy and is untested, and should be considered an initial draft only.

This looks like it should be possible to unindent, e.g.
let static_metadata = context.ir.static_metadata.get();
let records = &static_metadata.misc.meta;
// Guard clause: nop if there are no meta records
if records.is_empty() {
return Ok(());
}
context.meta.set(Meta::new(...));

looks right, I don't think meta can change global metrics

Hello!
This PR begins implementation of
metatable compilation for the Glyphs and UFO formats. This is a larger end-to-end implementation than my previous PRs, and so I am making an early draft to work on it publicly to make sure that it can be shaped from the beginning, and that it stays on track; all feedback and contributions welcome :)Implemented
metatable for the top few fontc_crater reportsTODO
StateSetconstruction inglyphs2fontirexpect(...), no type conversion clutter, etc)main(most of these are also flagged as inline TODOs, to be resolved before merge)
Will implement #1113
Note: this is a personal contribution independent of my employer, and so I've submitted from a fork under my personal profile and email to make this distinction
