When I submit an application through the app developer process in MyApps, I'm asked to submit icons in different sizes: 128px, 64px, 32px, 16px.
Where is each of these icon sizes used when my app is in Ubuntu?
At first glance:
128: App details view in the Software Center, Alt-tab Switcher
64 : Dash, and resized to 48 for the Launcher and the Software Center tiled view
32 : Software Center list view
16 : Some places on the desktop (Nautilus list view?) and probably in the software updater for 12.10 (https://twitter.com/dylanmccall/status/205418733206904833/photo/1/large)
