In https://bugs.webkit.org/show_bug.cgi?id=72411, I'm adding a linearized sRGB ICC profile to WebCore. I'm not enabling it for Windows for now, in order to not cause any behavior change there at all (Windows also doesn't support linear generic RGB via CG, which is what was previously being used, see http://webkit.org/b/31363. However, using an explicit ICC profile *should* mean that we can make this work on Windows without any CG changes -- it'll just require some testing.
Ugh, what a boring bug 80,000.
