    This method generates an OpenGL/JOGL MipMap structure, assoiates it with
    the given image reference and activates.

    The method keeps track of all images activated, and take that history into
    account to pass the image data to the graphics hardware only once. Note that
    this method creates and use an OpenGL/JOGL compilation list for each image,
    to ensure optimal performance.

    \todo
    In applications with changing images, the memory list of compiled lists
    and the list themselves should be cleared, or not used. This will lead to
    the creation of new methods.
