Comment 7 for bug 484420

I changed the shape of the buttons to have 3D look, but I dislike the final appearance. I attach two captures, the first one with non-homogeneous buttons, which looks quite ugly because each one has a different width, and the second one with homogeneous buttons, which makes the interface too wide.

The original reason to remove the pop-up was to make them look like a button box (which didn't have that popping up effect in old themes).
