Minimizing or hiding the window are different use cases.  Now, I'm not 
100% convinced this use-case is absolutely required but historically, 
it's always come up in discussions of improving the qemu gui.

Imagine the following:

A user starts a VM at a physical box.  Everythings fine but he wants to 
return to his workstation so he closes the window.  He goes back to his 
workstation and connects to a VNC server (on a different X server).  He 
wants to now bring up the guest's display.

This cannot be achieved with a gui in the same process as qemu.  Is it 
necessary to support?  I don't know.

I'd love to just replace the SDL display with GTK + Cairo.  I'm even 
somewhat inclined to suggest linking to python so that the gui can be 
written in python...
