Okay I've done some of this work on ui in my virtio-gpu branch of my qemu repo

http://cgit.freedesktop.org/~airlied/qemu/log/?h=virtio-gpu

I've added multiple display surfaces to a QemuConsole and add an idx
parameter in a couple of places,

Then I've hooked it up to SDL2, this lets me with my virtio-gpu to
create a screen panning two windows.
