This is mainly to help me test code builds under GCC faster than pushing to the remote and letting the build server do it. If someone without WSL installed selects the build target they'll get an error in their IDE, but no harmful impact other than that. The variables should be populated for any WSL2 installation. No idea about WSL1.
The whitespace in this file is showing significant changes because visual studio regenerates the whole file when a change is made, I didn't think it was worth reverting since it'll happen again next time someone makes a change (seems it defaults to spaces...). Added an entry to .editorconfig documenting the format used.
SDL_mixer can only stream a single music track
SDL_audiolib has unlimited streams.
With this change, we finally have streaming sounds (respecting
sfx_STREAM).
Audio options can now also be set via diablo.ini, which should help us
better diagnose the static noise issues.
Ensures the contents can be easily copy-pasted into the terminal from
most editors on all systems.
Otherwise, on Linux, you get 2 newlines for each newline in the source
when copying from VS Code.
Makes the code easier to understand.
Also makes building lists easier.
Also fixes focus indicator in SELLOAD_DIALOG (this type of bug is
impossible with the new structs).
Adds a USE_SDL1 build option to use SDL v1 instead of v2.
This is useful for porting Diablo on devices that don't support SDL2,
such as the RetroFW / OpenDingux devices (e.g. RG300 Retro Gaming Handheld)
Not yet supported:
* Fullscreen
* Upscaling
* Audio
