/**
* Small class to assist in properly closing an ImageInputStream instance
* prior to garbage collection. The ImageInputStreamImpl class defines a
* finalize() method, but in a number of its public subclasses
* (e.g. FileImageInputStream) we override the finalize() method to be
* empty for performance reasons, and instead rely on the Disposer mechanism
* for closing/disposing resources. This is fine when one of these classes
* is instantiated directly (e.g. new FileImageInputStream()) but in the
* unlikely case where a user defines their own subclass of one of those
* streams, we need some way to get back to the behavior of
* ImageInputStreamImpl, which will call close() as part of finalization.
*
* Typically an Image{Input,Output}Stream will construct an instance of
* StreamFinalizer in its constructor if it detects that it has been
* subclassed by the user. The ImageInputStream instance will hold a
* reference to the StreamFinalizer, and the StreamFinalizer will hold a
* reference back to the ImageInputStream from which it was created. When
* both are no longer reachable, the StreamFinalizer.finalize() method will
* be called, which will take care of closing down the ImageInputStream.
*
* Clearly this is a bit of a hack, but it will likely only be used in the
* rarest of circumstances: when a user has subclassed one of the public
* stream classes. (It should be no worse than the old days when the public
* stream classes had non-empty finalize() methods.)
