/**
 * Quick fix for #1061-swingx (which actually is a core issue): 
 * tree icons lost on toggle laf. Updates colors as well -
 * but beware: this is incomplete as some of super's properties are private!
 * 
 * Will not do more because in the longer run (as soon as we've fixed the editor issues) 
 * the JXTree's default renderer will be changed to SwingX DefaultTreeRenderer.
