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

It's unfortunate that I have to set color in css, and set icon type in js. Makes
me handle twice as much. Can we avoid that?

[lushnikov, 2016/12/19 19:55:21]

This is needed to support dark theme. It would be great to have a better build
system for icons to support dark themes; i have a few ideas regarding this.
