* Fix broken catacombs wall tile
When tile 15 is followed by tile 1 below, change tile 1 to tile 8
(left corner) to fix a visual glitch in the catacombs.
* Silence fmt catch warnings and guard SaveHelper copy
Turns out, `add_custom_target`'s `DEPENDS` argument can only
refer to outputs of custom commands in the same directory (i.e. the same
CMakeLists.txt scope).
Interestingly, this worked with all generators except parallel
make, so perhaps there some ongoing work in CMake to allow
cross-directory `DEPENDS`.
Works around this limitation by moving tests to the same scope
(`CMakeLists.txt` file) as assets.
This doesn't implement full sound support but stubs out most of the
sound code under SDL3, so that we can implement it piecemeal.
Implemented here:
1. Sound device initialization.
2. SVid sound playback.
Does not add a dependency on `SDL_mixer`: SDL3 built-ins
are enough to play SVid audio.
This does not actually add SDL3 support but adds enough
CMake stuff to make the following succeed:
```bash
cmake -S. -Bbuild-sdl3 -DUSE_SDL3=ON -DDEVILUTIONX_SYSTEM_SDL3=OFF -DDEVILUTIONX_STATIC_SDL3=ON -DNOSOUND=ON
```
`NOSOUND` is needed because `SDL_audiolib` does not support SDL3.
Now that the DOS SDL supports CMake, this is a much better option that
`configure`, because it lets us easily test out local changes to SDL,
e.g.:
```bash
cmake -S. -Bbuild-dos -DCMAKE_TOOLCHAIN_FILE=CMake/platforms/djcpp.toolchain.cmake \
-DTARGET_PLATFORM="dos" -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTING=OFF \
-DFETCHCONTENT_SOURCE_DIR_SDL2="${HOME}/diasurgical-SDL"
```
Ubuntu 20.04 is going EOL in May.
Ubuntu 22.04 CMake is 3.22.
Debian stable CMake is 3.25.
Debian oldstable (EOL in 2026) has CMake 3.25 in bullseye-backports.
Collects transitive object library dependencies in the topological order
and adds cycle detection.
Now transitive dependencies are actually all linked.
This does not fully address the issue of most everything
being a giant library but it's a start.
Note that the libraries are OBJECT libraries, so they
may (and currently do) contain references to missing
symbols.
Also fixes the implementation of transitive dependency
support for OBJECT libraries.
This mod renders a clock in the top-right corner
and is always available (disabled by default).
It is useful to have a mod available by default
as we work on mod support.
