* Utility class for managing OS resources associated with SWT/JFace controls

*
* !!! IMPORTANT !!! Application code must explicitly invoke the <code>dispose()</code> method to release the
* operating system resources managed by cached objects when those objects and OS resources are no longer
* needed (e.g. on application shutdown)
* This class is created automatically when you fiddle around with images and
* colors in WB. You might want to prevent your application from using this
* class and provide your own more effective means of resource caching.
*
* Even though this class can be used to manage these resources, if they are
* here for the duration of the application and not used then you still have an
* effective resource leak.
