exposay: centralize exposay's surfaces in their own square

Commit "exposay: add margins to centralize exposay" has centralized
the whole exposay, but that's not enough. The internal surfaces of
exposay are not centralized.

Each internal surface of exposay is a square, but most of the windows
are rectangular. Add margin to centralize exposay's surfaces in their
own square.
