Committed patchset #1 (id:1) as
https://skia.googlesource.com/skia/+/c6663dc36b157e40c8225130f5970a346f9ba7c3

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/1759653005/ by brianosman@google.com.

The reason for reverting is: Two major regressions from this change:
- Mac images may end up too bright, if they're correctly tagged as sRGB. That's
a sub-set of a much larger issue where L32 mode needs to suppress sRGB -> Linear
conversion of pretty much everything.
- Various low-end GPUs (Mali400 Android, iPad4) don't render in sRGB at all,
causing tests to produce no output at all..
