For some reason, setting the scaling on just `texture` still results
in bluriness. However, setting the default scaling mode on the renderer
fixes it.
Also, does a few more things the SDL3 way.
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.
Previously, an override font had to contain all the 256 glyphs in the
row that it was overriding. Experiments have shown that this would
cause huge file increase in CJK scripts (+200MiB or so).
Instead, allows the override font to only override some glyphs in a row.
For all glyphs (sprites) that have width 0, we now fall back to
the base font.
When rendering directly to output surface, PalSurface may need to be
updated after a flip. This is not actually needed on DOS but may be
needed on other platforms in the future.
I tried the interrupt handler approach but couldn't get it to work,
so for now we're back to loading and updating the progress bar
synchronously on DOS.
When compiling with clang, the compiler warns about the lack of return
statement in the non-void function fmt::format.
This fixes it by returning a default error string.
Tricks the compiler into skipping expensive
`uninit var analysis` (`-Wmaybe-uninitialized`) by using
a struct with state rather than separate variables for `best` /
`bestDiff`.
This has no performance impact.
Also optimizes lookup a bit further and moves some code that
does not need to be inlined to the cpp file.
