Because for some reason the hdiutil convert step would sometimes fail with "image corrupt" when given an image the hdiutil create step had just previously created. Too cursed for my pay grade; I took the easy way out.
Also make it easier to test tpt-libs builds locally by making it possible to point build.sh at a local tpt-libs repo and move installation of build dependencies to build.sh.
Fixes forward-incompatible behaviour introduced by 0ff08c276f. The idea is to have mod owners migrate from using mod_id.txt to using meson_options.txt, but if prepare.py unconditionally prefers the former, nobody can use the latter.
Removed in 59f89f9a46, brought back to minimize discomfort downstream. prepare.py will still default to the mod_id in meson_options.txt if mod_id.txt is deleted though.
Also fix font editor builds on windows and add more font editor builds to the ghactions workflow.
Funny, we don't really need resource.h anymore. The resource compiler does, but we don't.
Also make it and render get built as dynamic executables on ghactions, and disable dynamic+LTO, as it seems to be buggy in certain cases and isn't an important case.
Also Disallow linking against non-C++ system Lua, unless configuring with -Dworkaround_noncpp_lua=true, add -Dworkaround_elusive_bzip2 and friends, and get rid of the -image_base hack for macos.
All of these are options that are specific to our ghactions builds and not something we want downstream and package maintainers to be locked into using.
Both the debug and release jobs would upload artifacts, with the same name, which ghactions of course accepted without question. Snapshot 240 happens to have been released correctly (so all binaries are release builds), but that's just luck. I'd thought I'd fixed this problem with another commit, but turns out I hadn't.
Also factor out a bunch of variables so I won't mess up in the future.
Command line is limited in length on windows so meson/ninja puts it in a response file and passes that to the linker instead. Only problem is, ninja -v displays only the part of the command line where it tells link.exe where the response file is, not what's in the response file. So I just had the script print it. Care must also be taken for the script to properly fail if ninja fails, but not before the command line is printed.
Also add /GL and /LCTG to msvc command lines because they can't hurt. Right?
Also restructure meson.build and the ghactions workflow a bit, and enable -ffunction-sections and -fdata-sections.
Note that starcatcher uploads have not been tested and most likely don't work.
Also fix the first mouse click not being detected on windows with sdl 2.0.20. Apparenlty, we need SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH set to 1 for it to be detected.
