This isn't actually the data that callers usually want. Most of the
callers just want the bounds. The heading and length are trivially
computed from that. Add a class to contain the result so it's easier to
refactor.
This looks like it was just a typo. We want to join as late as possible
to allow flights coming from other airfields to take the best route to
the target that is safe, rather than joining as early as possible, which
isn't useful since pre-join and post-split are supposed to be safe areas
anyway.
The for_theater method is always called before for_airport is during
normal gameplay, but I'm writing a linter to show missing airfield data
that calls for_airport first.
This shouldn't be the case for anything shipped, but is typical when new
theaters are still being developed.
We could potentially add an `in_progress` flag to the theater definition
to make this only optionally tolerant, but since that code path would
rarely be exercised it's just likely to bitrot. This data isn't critical
to mission generation anyway, so this is fine. What we should do is add
some linters that document all the data that is missing though (and
ideally publish that to our docs).
Added weapons fallback data for the laser guided rockets, AIM-54's,
AGM-65 E/F, 4X Hellfire and TOW carried by US helis, rockets for them
to fall back to, all of the USSR IR missiles, R-3R, Mk-83 & Mk-84 and
adjusted the dates for the R-27ER &ET to 1990.
The next step in splitting up the layout and scheduling phases. This
facilitates splitting flights into two classes where one has a full
flight plan, but one used in the earlier phases of planning has only a
layout. Layout-only flights won't need TOTs, which will make them much
easier to work with once we've migrated TOTs from timedeltas to
datetimes.
Layout-only flights of course aren't actually usable, but it lets us
avoid dealing with the current sim time until we're certain the Flight
will even survive planning.
I'm not actually sure if we'll be able to split the two phases any more,
but this ends up being a nice cleanup anyway.
