Program icon in OS X
For a reason I don't get, the icon shown when switching programs via cmd-tab is badly pixelated (probably a 48x48 one), although I checked that the icon resource file contains resolutions up to 512x512 (mscore.icns).
I've a retina Macbook pro, and the dock icon is perfect (96x96?).
Just for the looks (and because I'd like to understand how OS X uses icons ;-)...

According to the Apple Human Interface Guidelines, retina macbooks require icons up to 1024x1024. Not sure where these icons are used but I guess the cmd-tab is a good candidate but I can't find any reference.
I created a task for next version #19128: Include 1024x1024 application icon for Mac OS X

I'm afraid there's more to it than just 1024x1024.
I run "old" programs like Journler that do not have upscaled icons, and nevertheless OS X does a correct job of interpolating the 512x512 version. In my case I really have a horrid icon when cmd-tabbing. Is it my machine, or can somebody reproduce this bug?
