Oh I see, there is a misunderstanding here, "edge" in my proposal does
not denote the monitor's edges but the window's edges.

So in your example, all 3 windows would be tiled on all 4 edges,
including the one in the middle as it's tiled against the montoir
edged at its top and bottom, and to the other windows on its right and
left edges.

This is why the description in my patch for each state reads "The xxxx
side of the surface is tiled, either to another surface or a monitor

In the light of this, I suspect Mike might also have misunderstood my
proposal,I did not understand why people kept referring to the
gnome-shell implementation of tiling...
