After some more experimentation with "WINDOWS,COLORS=...", I've come to the
conclusion that it is enough to leave some colors (5) for the widgets, and that
one doesn't have to start the widgets first. However, I prefer to allow IDL to
choose for itself how many colors are available. I think that when IDL does
this, it should automatically keep back whatever colors it will need for the
widgets, if not already created.
