That's not the problem. Doing that for each carrier is acceptable.
It's not like we'll have dozens of carriers around in the next time.
And even if: noting down offsets is something that we as modelers
do all the time anyway, as we need it in animations.
What would be a *very* bad idea, is to integrate all the offsets
in every single carrier capable aircraft. What we could do for now
is to just add the cat offsets to the model XML file (see attached
patch). You'd then find the coords in /ai/models/carrier/catapults/.
We'd just have to add such a block to each carrier, which is a
matter of minutes. More values could easily be added. It would be
more elegant to do that as a regular XML block, but that's not
supported yet.
