Oh, that's already a separate issue -- we have an external mechanism to
remap how global mouse position is translated to a window-relative
position. We need this as any window transformation changes the mapping
in a fashion unknown to the X server.

We can't reparent OverrideRedirect windows, so we'd have to use
something like the PseudoRoot extension that I developed years ago so
that non-CompositeManager applications would see this new window as the
'real' root and create their override redirect windows within that.

That's certainly possible, but prevents us from launching a compositing
manager to handle existing applications.
