There is an explicit offset of one pixel on the left when it sets up a
clip box in Agg. I don't know why this is there, but it dates back to
0.98.0, and earlier versions did something completely different. I can
only guess it was to compensate for an earlier bug in the precise
drawing of the axes rectangle. I can't explain why it would have
different behavior on Windows vs. Linux, though.
I have fixed this in SVN r6465 and am including a patch below (which
unfortunately requires a recompile).
Cheers,
Mike
