Provides a image and icon loading library using resource-bundle style key lookup.
This library abstracts away hardcoded image paths in your code, supports
at-runtime resizable icons (for accessbility), and provides built in broken
image indicator support. Automatic caching of images and icons using soft
references is also provided.
The design is very like Spring's MessageSource support and also builds off
Spring's core.io.Resource classes for accessing images from a underlying resource such
as a file, URL, or the classpath.
