 - Delegate to a `PrintStream` object (for things like `Throwable#printStackTrace`) using `#getLog` or similar.
   - If a level is not being logged (i.e. lower than `Log.enabled`), an empty print stream is returned that will ignore all method calls.
   - Each level's `PrintStream` also exists as a public static final field, such as `Log.WARN`.
