* Add sound stuff
* Maybe switch to PBR, or show both
* Add keyboard handling framework(s) and keybindings
* Add simple GUI library we use for SoundWell
* Add all of the stuff we use from Rubralib (our common functionality library)
* Add utilities to rebuild HDLLs on both platforms
* Fix Windows builds
  * Fillin the rc and icons and stuff in the windows-manifest, and make the windows build work.
  * Make the build-windows.sh script parametric so that it doesn't have all the target stuff
    and directories hardcoded. Maybe switch the functionality to the Makefile instead.
* Work out static compiling on linux, or at least platform-package or Flatpak builds
* More documentation about the various tips, tricks and discoveries that went into this.
* Publish on itch.io with a web build of the project as an advertisement of this repo.
* Maybe take this as an excuse to write our enhanced PBR renderer with shader support
