Carbon: resizing a frame on wrong "space"

[David Reitter]

When using the new "spaces" feature in Leopard, Emacs shows a bug when  
attempting to resize a frame.

To reproduce:

- configure "spaces" in 10.5 so that there are two vertically placed  
spaces.
- emacs -Q   (Recent Carbon port build from 22 branch CVS)
- move the frame to the other space (e.g. by dragging it to the  
[lower] edge of the screen)
- resize it (with the mouse)

What happens for me is that the frame is moved to the original space  
on which it was created while I'm resizing it. Then, it is moved back  
down.
