Sets the size of the surface in pixels. The compositor will display the

If you pass -1 for either value, the compositor will assign it and
If you pass 0 for either value, the compositor will assign it and
inform you of the assignment in the configure event. You must set your
anchor to opposite edges in the dimensions you omit; not doing so is a
protocol error. Both values are -1 by default.

implementation-dependent - do not assume that this region will not
actually be occluded.
This value is only meaningful if the surface is anchored to an edge,
rather than a corner. The zone is the number of pixels from the edge
that are considered exclusive.
A positive value is only meaningful if the surface is anchored to an
edge, rather than a corner. The zone is the number of pixels from the
edge that are considered exclusive.
Surfaces that do not wish to have an exclusive zone may instead specify
how they should interact with surfaces that do. If set to zero, the
surface indicates that it would like to be moved to avoid occluding
surfaces with a positive excluzive zone. If set to -1, the surface
indicates that it would not like to be moved to accomodate for other
surfaces, and the compositor should extend it all the way to the edges
it is anchored to.
For example, a panel might set its exclusive zone to 10 pixels, so that
maximized shell surfaces are not shown on top of it. A notification
might set its exclusive zone to zero, so that it is moved to avoid
occluding the panel, but shell surfaces are shown underneath it. A
wallpaper or lock screen might set their exclusive zone to -1, so that
they stretch below or over the panel.
Exclusive zone is double-buffered, see wl_surface.commit.
