Yes..., :), this is true. It's off by exactly one pixel when you construct a
box around it. I'll see what I can do about fixing it, I tried to fix that
before, and remember that I made a descision to make it one pixel smaller
than the box, but for the life of me I can't remember why I couldn't just
"fix it". One thing to note is that the algorithm because of symmetry can
only construct even sizes, it will just ignore odd ones. (The bit shift
downward on the width and height in the very beginning dumps the "oddness" in
the width & height) I'll re-pull from CVS and post a diff to the present one
if I can get a better behaviour from it. I should probably document how it
works too...
Thanks,
Shane Nay.
