Leaving bug open, patch simply added expectations.

Mike/James, any comments on these failures? The results on Win & Linux look very different (they have gradients) from the Mac results.
Mike Lawther
Hi Adam - the gradient look is because Skia is doing a bilinear interpolation instead of a nearest-neighbour - hence the blurring of the edges. The tests are scaling a 2x2 image to 100x100, hence the obviousness of the difference.
I need to look into this - Skia is doing something different with InterpolationQualityNone than what I expect.

Ping. It's been three months, this may have fallen off your radar.
