Comment 4 for bug 860037

Fixed. The commit robot missed it because I typed "Fixes-bug" instead of "Closes-bug" again.

    Increase DPI of test hid_png3

    Since the nanometers conversion, hid_png3 has failed due to rounding
    changes. I have changed the test's output DPI from 300 to 600, to
    decrease the chances of this happening in the future.
