Both calls to bordwalk() are now controlled by the "-n" switch.

The alternative computation of the destination region, which is more
robust[1] but significantly more expensive, is still disabled. It
should probably be removed; if the existing computation of the
destination rectangle doesn't produce the correct answer, the
computation of the source rectangle will probably be wrong also.

[1] Except that it has a bug. As proj_f() overwrites its input,
ycoord1 would need to be re-initialised on each pass of the inner
loop, along with xcoord1
