By looking into the code, seems that the coordinates returned by
bwboundaries should be (rows, columns) at least when the object is
only one point. This is opposite to what the help text says.

When the object is larger than 1, it uses __imboundary__ which is
written in C (I don't know how to read C so I can't help) so maybe the
coordinates are returned as (columns, rows) as the help text says.

Should the help text or the function be corrected about the order of
the coordinates?
