Hey, there's no need for that. You have been sending rather a lot of stuff
lately, you know, you can't blame people for not quite being able to keep

Andrea, I would like to point out that having methods like
doLayoutInWorkspace and so on have nothing to do with the viability of your
LayoutCombinator class. These methods have only to do with implementing
PerWorkspace in particular. In fact, I rather liked your LayoutCombinator
class and would like a chance to try implementing PerWorkspace using it
together with sjanssen's approach of special messages sent by a startup
hook. I would like to ask if you can just re-push your LayoutCombinator
class and CombinedLayout combinator, without making any changes to
PerWorkspace? That way it will not break anything and we can play around
with implementing things in terms of it.

Again, you seem to be confusing the issue of the type of 'description' with
the problem of getting PerWorkspace to work with xinerama. The above code
still would not work with xinerama, which is my main goal. It also still
does not work with messages that may be sent to a non-focused workspace.
That implementation IS ACTUALLY working and has been in xmc repository

No, it wasn't; there is still the issue of messages sent to non-focused
workspaces, which probably wouldn't cause any problems most of the time (so
it appeared to work) but could cause subtle bugs. I sent an explanation of
this to the list earlier.
