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.
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"
```
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.
Texts adapted to fit well in different menu options where the space is limited.
Some changes are made to be consistent with the rest of the translation.
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.
