Hmm, dragging gets started when the view of the NSImageView is editable
and this is set to YES in the init method of the view. If you are sure
that the default for Cocoa is different, I am willing to change this

This is a well know annoyance. We probably shoudl not use the image
directly, rather create a smaller one and use that for the drag display.
Are you willing to implement something here?
