  ### Issues:
  # * Set us to only use software rendering with `-Dprism.order=sw`, had a hard time
  #   getting `prism_es2` happy with NixOS's GL/GLES.
  # * Currently, there's also a lot of `Failed to build parent project for org.openjfx:javafx-*`
  #   at build, but jar runs fine when using `jreWithJavaFX`.
