/**
 * Traverses through components hierarchy and prepares screen shot for every component passed in

 * 
 * @param component
 *          the branch hierarchy root component.
 * @param componentImages
 *          the {@link Map} of components which screen shots should be made for. This map would be
 *          filled by prepared {@link java.awt.Image} instances.
 * @param rootComponent
 *          this branch hierarchy root component.
