Subject: [PATCH] Calculate better extents for the configured displays
 arrangement

Find out the bottommost and rightmost outputs in the arranged space, so
the represented outputs in the arrangement widget use as much space as
possible, instead of allocating enough space to allow any kind of
configuration beforehand.
