`SDL_VIDEODRIVER=wayland` seems to be a requirement for GLEW to
initialize when using glew-egl.
`SDL_VIDEO_WAYLAND_WMCLASS` associates the application with the .desktop
file (in GNOME Shell, at least, if not other Wayland desktops).
glew alone is not enough to propagate explicitly:
```

```
Let's add all SDL and alsa-lib as well. Instead of using propagatedBuildInputs
let's embed store paths into a shell wrapper.
The Mindustry source code makes heavy use of internal Java APIs that
were deprecated in Java 6 and removed in Java 16. It also makes use
of features that require Java >=14.
The author is not ready to provide compatibility with any
maintained Java version at this time.
- make pre- and post-{build,install} phases usable for the main derivation
- replace uses of stdenv.lib with just lib
- specify which buildInputs are only needed for the client
- reduce the buildPhase of the fixed-output dependencies derivation to
only download all dependencies, instead of building the full thing.
- add wayland variant, which is linked against a different variant of
the glew library to run natively using SDL_VIDEODRIVER=wayland
- use jdk (Java 15) instead of jre (Java 8) at runtime
- use new copyDesktopItems hook
* update two explicit references to jdk14 to just jdk, which no longer
points at jdk8 after #89731.
* patch an explicit -XX:+UseConcMarkSweepGC to -XX:UseG1GC, as the
former now throws an error (after having been deprecated since jdk 9)
