Asking users for opinion - padding or not?

[Rush]

Do you think Font-Awesome-SVG-PNG should try to put icons in a square by adding padding or keep it faithful to the original sizes?

For example http://fontawesome.io/icon/building/ and http://fontawesome.io/icon/building-o/ have a different width and forcing padding to make them square can have some alignment issues.

But I would still icons http://fontawesome.io/icon/battery-full/ as kind of an exception as they have wildly bigger width.

Newest versions adds some vertical padding for pixel perfection but only up to 16 / 14 of the original size. If icon was originally square, the same padding will be applied to keep it square.

Feedback welcome.
