Mailbox Icons

Amidst an updated iPhone app (shipping soon), new Android app, and upcoming Mac app, we took the opportunity to update Mailbox's iconic in-app icons. The previous set didn't have a consistent visual weight, and the strokes were different from icon to icon.

For the new set, every icon was drawn on top of a 4 by 4 pixel grid in order to make them easy to resize for all the different sizes we need on all the different platforms.
