Description Jon Lee 2012-04-04 11:23:52 PDT
While unskipping the tests in b80630, I found that there are still minute differences between the results of WK1 and WK2. 14 of the 18 tests in that patch pass the pixel test, but fail the hash. If you run those tests with -tolerance=0, then they fail completely.

  css3/filters/crash-filter-change.html -> pixel hash failed (but pixel test still passes)
  css3/filters/effect-brightness.html -> pixel hash failed (but pixel test still passes)
  css3/filters/effect-contrast.html -> pixel hash failed (but pixel test still passes)
  css3/filters/effect-drop-shadow.html -> pixel hash failed (but pixel test still passes)
  css3/filters/effect-grayscale.html -> pixel hash failed (but pixel test still passes)
  css3/filters/effect-hue-rotate.html -> pixel hash failed (but pixel test still passes)
  css3/filters/effect-invert.html -> pixel hash failed (but pixel test still passes)
  css3/filters/effect-saturate.html -> pixel hash failed (but pixel test still passes)
  css3/filters/effect-sepia.html -> pixel hash failed (but pixel test still passes)
  css3/filters/filter-repaint.html -> pixel hash failed (but pixel test still passes)
  css3/filters/filter-with-transform.html -> pixel hash failed (but pixel test still passes)
  css3/filters/nested-filter.html -> pixel hash failed (but pixel test still passes)

Ultimately, many of these tests might fail the pixel hash. I'm only citing the ones that were known failures in b80630.
