fuzzy This allows a test to pass if the pixel value differences
are <= 2. It can also be used with '!=' to ensure that the
difference is greater than 2.
fuzzy(maxDiff, diffCount)
This allows a test to pass if the pixel value differences are <=
maxDiff and the total number of different pixels is <= diffCount.
It can also be used with '!=' to ensure that the difference is
greater than maxDiff.
fuzzy-if(condition) If the condition is met, the test is treated as if
'fuzzy' had been specified. This is useful if there
are differences on particular platforms.
