The HImagePanel class displays an image usually representing buttons which a user can highlight with a mouse click and which trigger user defined actions.
An image panel object consists of 3 HOOPS images which must be stored in separate HMF files. One of them represents the visual representaton of the unselected panel while the other represents the selected state. The third image defines regions inside the panel (based on the rgb values in the image) which trigger execution of a user supplied callback function.
