NSView and array of moveable NSImages

I have read elsewhere on this forum that it is unwise to overlap NSView
subviews within an NSView, as it's not properly supported, or something like
that.

Therefore, I have an NSView into which I am drawing an array of NSImages. I
would like to be able to move them around by dragging the mouse, but feel as
though extensive mouse and z-index visibility testing is overkill, but after
a good deal of surfing cannot see an alternative.

Is there a well trodden path to maintaining this sprite-like behaviour in
Cocoa?

Many thanks,

Fen.
