I've decided to punt this issue to 2.4 and just use an internal
setting inside gtkdnd.c to handle the stock/pixbuf icon types.

The result then is that for 2.2.x:

 - Except for drag icons created from pixbufs/stock images,
   drag icons will be confined to a single screen and the default
   drag icon used on other screens.

 - We won't be able to implement app-external window migration
   without an additional API addition. (I doubt we would
   add the implementation in the 2.2.x series anyways, so 
   it doesn't really matter.)

I don't think these limitations are serious enough to be worth
blocking on this issue at the moment.

I've filed the problem as:
