/**
 * Workaround for bug in swing invalidate/validate concept. Swing is caching

 * fine. But in case a validate is in progress and part of the ancestor tree
 * is already layouted based on old sizes then the caches are already set, but
 * the valid flag is still false. Therefore this method can be called which
 * will invalidate all ancestors *including* those that are still invalid in
