Makes sense I think, but for merging we need:

This is where it starts getting tricky. vboxvideo is out of tree. In
theory I could look at getting it merged, but that needs time I am
rather short of (I am the only person maintaining that driver and it is
just one of my responsibilities; and there are some bits there that are
probably too ugly to merge as is). I don't think I am really the person
to be doing this for qxl/virtio-gpu as that required adding the support
to qemu too.
Not only kernel driver and qemu. Right now neither qxl nor virtio-gpu
can communicate the actual layout back to the host. So this also
requires changes to the guest/host protocol (i.e. the virtual hardware).
- some userspace to take advantage of it
As I wrote, mutter would be the first candidate.
Do you have any feedback from mutter developers on the two approaches
(touchscreen-style autoconfig or x+y offsets)?
The first time I wrote to them no one responded to my e-mail[1]. I
could try again, asking just that question, though my plan at this time
was just to submit a patch. (For Daniel, I am looking at our source
code again to see if I can get it in a merge-able state with a
reasonable time investment. Then there would be the "some driver to
implement".)
