Skipped files give us no way to track pixel failures separately from other types of failures. If we start using a test_expectations.txt file we can track these and get a clean test run both with and without pixel tests enabled.

Maybe that should go in mac-leopard? LGTM.
test_expectations files should generally be as portable as possible, because maintaining multiple versions is a hassle, and one hopes that most bugs are cross-platform/cross-version, rather than version-specific.
