<Swing Dev> Background/Foreground colors and Gtk Look and Feel

[Alexander Potochkin]

Hello Gentlemen

The truth is that L&F can completely ignore the background and 
foreground properties

see JComponent.setBackground() javadoc:

      * It is up to the look and feel to honor this property, some may
      * choose to ignore it.

So for reliable implementation I'd recommend to choose another technique
