Instead of this, change the size of the icons. They are not 32x24.

I tried this, two reasons I decided to keep this as-is:
1. Since margin is not symmetrical, this line will stay, but with different
numbers
2. Since icons are colored via linear-gradient, and the size of the icon gets
changed, every gradient has to be changed as well. This seems just not worth it
