The color profile switches automatically for me on running pixel tests with Lion or SL. How is it even possible that we got images with different color profiles for mac results?

> It appears that these files have come from various sources, including Tony Chang's embedding of checksums in image files, and new expected results created on Lion.
> I think we should be consistent about color profiles, and in a way that doesn't break pixel tests. Does anyone want to vote one way or the other?
> Once we decide, we should also have some kind of protection against adding new pixel results which don't follow convention. Maybe webkit-patch can be taught about this.
