I would assume that, much like icons, a framework should typically prefer the smallest image that does not need to be scaled up.

e.g. with icons:
34x34 - 128x128 is scaled down
33x33 - 128x128 is scaled down
32x32 - use the 32x32 native version
31x31 - 32x32 is scaled down
30x30 - 32x32 is scaled down

Is this an observation of current behavior in Cocoa or a wishlist? If it's the former, I'd like to know how you achieved it. My experience with NSImage is that at 31x31, 128x128 is scaled down rather than 32x32, which makes for a suboptimal appearance.
It's actually an observation of the Finder's behavior. I do not know what APIs the Finder uses internally to get this behavior.
Upon experimentation I find that the Dock does not work this way, unfortunately.
