aren't setters/getters methods used only for objects that need to have

view? humm... would you even need to have setter and getters for
animation?
Since a property of an image view is its image, it's natural to have
setters and getters for that property. What a client code might use
them for is none of its business.
It's very common to change the image in an image view, for example a
UI might show an icon or preview of some object that is selected and
the selection can change... So everything you've written after
"assuming the..." is just reflecting your personal limited use of
NSImageView that has no real bearing on the design of the object.
