This is annoying that the backgroundColor is ovverriden by Glamour-Morphic-Theme.
Because now backgroundColor has been removed from the system and the Polymorph-Widgets is dirty.
and I lost 40 min because I thought that this was my new changes that were producing this.
Now if I reintroduce backgroundColor then Glamour is dirty. So I will do it and Glamour should merge or I do not know
what.

But we should not integrate systems with override and try to remove override as much as possible.

��� that :)
Which means that now we have a long way to polish them until Pharo4 release.

Please test and provide feedback :)
