drag & drop of images

[Riccardo]

Hello,

I noticed that in price trying to "grab" the image with the mouse 
detaches it and seems to attempt a drag-and-drop. On Macos-X the same 
code doesn't do this. Is there a wrong default inside GNUstep? I find 
this behavior disturbing.
Furthermore, the drag operations attempts to show the whole image that 
fits inside the view, thus it can eb quite large and it can really make 
your computer busy if it accounts to a bigger image.

cheers,
  Riccardo
