CVS commit by harris: 

Eliminating flicker in KPlotWidget.  Added "WNoAutoErase" flag to 
QWidget ctor.  It works well!

(note: I first tried to add "setBackgroundMode( QWidget::NoBackground )" 
to the KPlotWidget ctor, but this didn't stop the flicker.  This is 
strange, because that's how I got rid of the flicker in the SkyMap 
widget.  SkyMap doesn't use WNoAutoErase, yet it is flicker-free.  Odd.)
