Thanks.
This seems to speed up things a lot :-).
A small issue with this is that the script
sometimes shows up behind the morphs 
on the scene. 

I think the stepTime for the update of the world icon
could be set to several seconds. The icon is really small 
and most details don't show up anyway. Only major changes 
like change of background color and changing somethings
bigger than 1/4 of the screen is noticed. 

Yet another thing is when I bring the color picker up.
It flashes all the time when its in front of a flap/tab. 
Is it not modal, so bringing it 
to front once should be enough ?
