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.
