Mac OS Icons
====================================

NSStatusItem Icons
------------------------------------

See: http://alastairs-place.net/blog/2013/07/23/nsstatusitem-what-size-should-your-icon-be/

Normal displays:
  21px height, but should include 3px space at the top and bottom of the icon
  in order to look in line with the system icons.
  The icon can be up to 22px wide (no space is needed).

Retina displays:
  41px height, but should include a 6px space at the top and a 5px space at
  the bottom in order to look in line with the system icons.
  The icon can be up to 44px wide (no space is needed).

The empty space on the top and the bottom is not required, and is flexible. It
still looks fine if a few pixels poke into this space, and even some system
icons do this.

Unlike in the past, the Mac menu bar can now be light or dark colored, so the
icon should look good on both backgrounds.

Application Icons
------------------------------------

App icons must be 1024×1024 for the app to be accepted in the Mac App Store.
