You can change the behavior of the display by adding new icons, so it's
necessary to test which icons are present in order to draw the correct
display. We test for availability by getting an icon and checking if it
wasn't found. The filesystem is pretty well cached on each of the
platforms, but if we measure performance problems we could build
another cache.

This seems less than optimal. Shouldn't the app know which image it
should display, rather than try the file system for different images?
