[Python-apps-team] Bug#681051: xpra: menus pop up off-screen

The rest of this bug should now be filed against Xorg/dummy driver as
there is nothing left to do in Xpra itself.
1) the dummy driver should handle adding new resolutions on the fly via
Randr
2) Xorg should allow us to add new dummy screens on the fly so we could
ensure that the virtual display layout matches the client's precisely

The support code for this already exists in recent versions of xpra: we
expose not just the total display dimensions but one for each screen,
and I have randr code to try to add the resolution to the server then
set it. Unfortunately, dummy does not support "full" Randr.
In late 2011, I had asked for help on how to provide the patches against
Xorg but have not received any answer.
