It looks as if this would be possible using the place geometry manager
and possibly using a fake window. Some testing shows that place
doesn't have weird repacking behaviour since the geometry is never
propagated anywhere. It is worth investing in since it looks very cool
when I do some toy experiments using the full presence control panel.
Likely to show up other issues.
