Suggestion for Porcelain Windec

Well, that's possible to make the closer and the minimizer less thin. That's easy.

But the halo is a much more complicated thing. Besides, I think if we add a halo around the buttons graphics, there should also be a halo around the title frame.

I'm preparing a final version to correct all the bugs I noticed with my everyday use. (Title text must be higher. Title frame must be rounder. A minimal size must be respected.) I'll see what thicker closer and minimizer look like... but just a little thicker.
