For the software rendering code path, I suspect it is because RasterSource::PlaybackToCanvas is not given an SkCanvas that is tagged with a color space.

Adding browser pixel test for linear-rgb support in Canvas.

Recetnly the proper plumbing has been added to Canvas such that it
renders when linear-rgb color space is used
(codereview.chromium.org/2425113002/). This change adds a browser pixel
test to see if the rendered Canvas is properly displayed.

Add more robust gfx::ColorSpace<->gfx::ICCProfile conversion

When a gfx::ICCProfile is created from a gfx::ColorSpace, store the
original gfx::ColorSpace that it was created from, so that when
gfx::ICCProfile::GetColorSpace is called, we can return the exact same
original object.
