Create an invisible frame -?

[David Reitter]

Hi -
can someone tell me how to create an invisible frame?
I tried setting visibility to nil in default-frame-alist, but that  
doesn't do the job.

The reason why I want to do that is to create the frame, resize it  
(and change other frame parameters depending on the buffer that is to  
be displayed) and then make it visible, so it won't dance around on  
the screen.

Thanks
Dave
