This would be a usability regression. It is very unhandy to switch
between grabbed and ungrabbed, specifically for alt-tab, when working
with guests vs. host windows. Look e.g. at how rdeskop works in this
regard. That's why I introduced this feature to QEMU, and I would not
want to see it die again with the introduction of GTK.

OK for aspect-ratio-correct scaling of the guest view from my POV. And
if there is a use case for the old behavior, we could still add a switch
to the menu for selecting the scaling mode.

VGA is (mostly) x86. Also, we may once have multiple guest screens,
maybe even multiple types of them. So picking up some telling front-end
name would likely scale best.
