/**
 * Retrieves an overlaid image from the internal repository of images.
 * If there is no image one will be created.
 *
 * The decoration overlay for the base image will use the array of
 * provided overlays. The indices of the array correspond to the values
 * of the 5 overlay constants defined on {@link IDecoration}, i.e.
 * {@link IDecoration#TOP_LEFT},/*from  w w  w . j  a  v  a 2  s  .c  o  m*/
 * {@link IDecoration#TOP_RIGHT},
 * {@link IDecoration#BOTTOM_LEFT},
 * {@link IDecoration#BOTTOM_RIGHT} or
 * {@link IDecoration#UNDERLAY}.
 *
 * @param baseKey the base image key.
 * @param overlayKeys the keys for the overlay images. Must be
 *    String[5], i.e. string array of 5 elements. Put {@code null} as
 *    an element to the array if no overlay should be added in given quadrant.
