I did a quick spike to give a better idea of what I am talking about.

1) Here is the code:
better-shadow.cs <http://forum.world.st/file/n4817499/better-shadow.cs>  

2) Here are some pictures:

I decided to always have rounded shadows -- even for rectangular
windows/menus.

Do we want to have this with a preference in trunk?

Best,
Marcel

P.S.: Yes, resizing large (> 1000 pixels) windows gets slow on my Core i7.
:-D
