The 'fails' and 'fuzzy' annotations do not interact correctly
When a reftest has both a 'fails' annotation and a 'fuzzy' annotation, fails should be evaluated with respect to the fuzzy annotation, not with respect to the underlying test. An example of the problem: > fuzzy(5,999) fails-if(!cocoaWidget) != test.html ref.html The intention here is to use the behavior of fuzzy with != to make sure that the maximum difference between test.html and ref.html is more than 5, and annotate that this test fails on non-OS-X platforms. Unfortunately, that doesn't work, because the fails-if annotation ignores the fuzzy annotation. Instead, you get a TEST-UNEXPECTED-PASS if test.html and ref.html differ on some OS X platform, even if the maximum difference is less than 5. There is actually no way to express this correctly with the reftest harness right now, as far as I can see. I've tried many possible ways of expressing this and they don't work. This seems related, but different, to bugs like bug 720684.
