        Add Leopard specific pixel test results where needed, most just show marginal 1px diffs, or even invisible changes,
        only the filter test changed, but it visually looks the same - must be a Cg difference to the Snow Leopard baseline.
        Now the pixel tests pass again with --tolerance 0 on my Leopard machine.
