Add fuzzy-max option
In some cases we want to support differences in reftests greater than 2 (skia in particular). I feel that it's better to have this configurable rather than disabling the tests entirely.
I actually think the maximum number of different pixels, and the maximum difference per pixel, should be mandatory parameters to 'fuzzy'/'fuzzy-if'.

Add max values to fuzzy/fuzzy-if instead
Alternative option that roc suggested.

Add max values to fuzzy/fuzzy-if instead v2
Updated tolerance values to match the failures seen on tinderbox, and updated for new fuzzy tests that have been added since the previous patch was posted.
dbaron: Do you mind if roc reviews this?
Presume the other patch is now obsolete?
This patch should have updated the documentation. This has now been reported twice; see bug 729784.
