pdftoppm sometimes renders white borders

When passing a resolution to pdftoppm, the resulting image can get a thin (<1px) white border on the bottom and right edges. For example, the attached test.pdf is all black, but pdftoppm -r 203 test.pdf > test.ppm generates an image with a thin white line at the bottom.
(The Impressive viewer uses pdftoppm in this way, and such artifacts are readily visible against the black background there.)
