Cosa è cambiato in EDuke32, build per build

Mesa conveys most of the useful info through there, not linking.

Bugged since forever and would have floors and ceilings stay put when alt-wheeling in mapster.

need lights. This should save a bit of work in the general case with skies, too.

Classic relative scaling apparently had some numerical artifacts related to length of firstwall. Cribbing the logic added in 6fc6b7d5 in Polymost along with bumping the precision of the intermediate terms seems to make it line up fully. Rooftop floor in E1L1 and surrounding ledges are good test cases for this.

The visibility calculation relies on the distance, which might not be entirely accurate in rotatesprite, so maybe it'll be too dark in some cases.

TODO: figure out wtf is wrong with rotatesprite, linear filtering.

arrays; any write access to them will run the corresponding hook and write to the [sector/wall/sprite/tsprite]clean array. Note: tsprite and sprite use the same hook and require running a few more instructions per access in order to disambiguiate; this could be made more optimal (like the other arrays) by clearly separating the types in the game code. Note #2: taking a member's address currently marks it dirty because of tons of helper functions across the editor code. I don't know how many read-only accesses we have after taking a member address, but it could also be fixed with some finessing of the code.

Lightmaps are already opt-in anyway.

And hook them up to cstat 128 (half-submerged, 'c' in mapster).

And hook it up to SE cstat 64 ('1' in mapster32). This disables both lightmaps and shadow maps for the spotlight; please let me know if you have a usecase where you want lightmaps but no shadow maps for specific lights.
