- Class providing a shared library of Imageset objects to the system.
-
- The ImagesetManager is used to create, access, and destroy Imageset objects. The idea is that
- the ImagesetManager will function as a central repository for imagery used within the GUI system,
- and that such imagery can be accessed, via a unique name, by any interested party within the system.
