Mike, I will make sure this lands after your CL :).

Herb, let me know if this is along the lines of what you were
looking for.  I believe this will allow us to compare sRGB
profiles using a pointer compare.

File src/core/SkColorSpace.h (right):

https://codereview.chromium.org/1945693002/diff/1/src/core/SkColorSpace.h#new...
src/core/SkColorSpace.h:123: static sk_sp<SkColorSpace> NewRGB(SkGammas gammas,
const SkFloat3x3& toXYZD50);
Reverse parameter order to match the rest of the file.  I find it logical to
list the objects in the order that they should be applied to the encoded data.

PTAL, I've rebased and added a test.
