/**
* This class provides convenience access to many of the resources required
* by the workbench. The class stores some images as descriptors, and
* some are stored as real Images in the registry. This is a pure
* speed-space tradeoff. The trick for users of this class is that
* images obtained from the registry (using getImage()), don't require
* disposal since they are shared, while images obtained using
* getImageDescriptor() will require disposal. Consult the declareImages
* method to see if a given image is declared as a registry image or
* just as a descriptor. If you change an image from being stored
* as a descriptor to a registry image, or vice-versa, make sure to
* check all users of the image to ensure they are calling
* the correct getImage... method and handling disposal correctly.
*
* Images:
* - use getImage(key) to access cached images from the registry.
* - Less common images are found by calling getImageDescriptor(key)
* where key can be found in IWorkbenchGraphicConstants
*
* This class initializes the image registry by declaring all of the required
* graphics. This involves creating image descriptors describing
* how to create/find the image should it be needed.
* The image is not actually allocated until requested.
*
* Some Images are also made available to other plugins by being
* placed in the descriptor table of the SharedImages class.
*
* Where are the images?
* The images (typically gifs) are found the plugins install directory
*
* How to add a new image
* Place the gif file into the appropriate directories.
* Add a constant to IWorkbenchGraphicConstants following the conventions
* Add the declaration to this file
