I'm trying to figure out how to be able to drag an NSImageView

NSImageView.
Basically, I'm trying to drag a grey box around over the top of a
picture. I can programmatically move it around but I can't seem to
find the right code to allow me to drag it around.
You don't actually drag a *view*, you drag an image. Pedantic,
perhaps, but important.
When you start a drag, you specify the image that will be dragged.
See NSView's -dragImage:at:offset:event:pasteboard:source:slideBack:,
as well as "Dragging Sources" in the "Drag and Drop Programming Topics
for Cocoa" reference.
