No, we cannot protocol-wise, as that would expose the global coordinate
system to the clients, and likely be misused to implement an absolute
"XMoveWindow".

For the "remember layout" functionality, we need to come up with
something else. Maybe ask the server to generate a per-surface "cookie"
from the current server-private state (transformations, absolute
position...), that when restoring a layout, could be sent back to the
server between surface creation and initial attach (mapping).

The client itself would save everything it already knows: surface size,
state like maximised, etc.

What that cookie is, just a handle for server stored data or somehow
opaquely encoding the state, is an implementation detail.

I haven't discussed with anyone about this, it's just my first guess on
how it might work.
