Currently the JFXtras workaround extracts to a tempdir, but the better approach would be to load the DLL's as resources directly from the jar. No need to extract then and that also would work fine for runtime.

The DLL are never formally installed, they just have to be present on the classpath to be loaded as a resource. Multiple jars containing the DLL's are classpath errors and should be resolved. The workaround in JFXtras extracts to a temp dir with the JFX version in the name, so that works as well.
