The former is not very general (why must borders be split into top,
left, bottom, right?) and suffers from (probably fixable) semantic
problems (what about the little squares in the corners?  Which piece of
the border do they belong to?).

The latter needs no extensions: simply give the window a border-width
of zero and make it a child of another window which sticks out by the
desired amount.  Handle expose events on this second window as
indications that pieces of the "border" need to be redrawn.  The second
window might instead be a sibling of the first instead of the parent,
if that turns out to be more convenient.  In particularly extreme cases
it might even be four windows (top, left, bottom, right) instead of one.
