#1 Don't round image boundaries

[Frederick A Niles]

I'm using potrace to convert map pieces into eps and
then put them together. However, potrace is rounding
the edge of each piece. I understand and appreciate
the fact that potrace rounds edges within the image,
but I don't think it should round the very edge of the
original raster image.

To clarify, if an image has the whole right side black,
then the output vector eps should have a line going
from the top to the bottom of the vector image on the
right side. Currently the edge will come out slightly
curved in the vector version, with the corners not painted.

This is hard to explain, please write back if you don't
understand.
