Provides image loading capability for Java FX.

A plugin for loading a given format is added by creating an `ImageFormatDescription` to provide the principal attributes for recognizing images stored in the format, an `ImageLoader` which performs the actual loading of the image data and metadata, and an `ImageLoaderFactory` which is able to create an `ImageLoader` for a stream of image data stored in the format. The `ImageLoaderFactory` is registered with the `ImageStorage` object which manages all `ImageLoader`s and which also supplies convenience loading methods for application use.
