This CL patches the `png` crate in a way that corresponds to the following upstream PRs: * image-rs/image-png#526 - baseline to make subsequent patches easier to apply * image-rs/image-png#528 - `mDCv` and `cLLI` * image-rs/image-png#529 - `cICP` This CL is a prerequisite for rolling Skia beyond http://review.skia.org/917216 Bug: chromium:376758571 Bug: chromium:376550658 Change-Id: I5a70fccd71ae4295b62f7291a5fd3809f0d53860 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/5999738 Commit-Queue: Łukasz Anforowicz <lukasza@chromium.org> Reviewed-by: Adrian Taylor <adetaylor@chromium.org> Cr-Commit-Position: refs/heads/main@{#1385066}

This CL propagates the data from the `cICP` chunk into `SkEncodedInfo::ICCProfile`. Dependencies: * This CL unblocks enabling the `PNGTests.cicp` test in the Chromium CL at https://crrev.com/c/6013356. * This CL depends on the new `SkColorSpace::MakeCICP` API that was recently added in https://crrev.com/c/5999738. This CL patches the `png` crate in a way that corresponds to the following upstream PRs (rolling this CL into Chromium depends on https://crrev.com/c/5999738 which included the same patches): * image-rs/image-png#526 - baseline to make subsequent patches easier to apply * image-rs/image-png#528 - `mDCv` and `cLLI` * image-rs/image-png#529 - `cICP` Bug: chromium:376758571 Change-Id: I1e550b1eba4d629ff4337d85daa5656ac03f3a5a Reviewed-on: https://skia-review.googlesource.com/c/skia/+/917216 Commit-Queue: Łukasz Anforowicz <lukasza@google.com> Reviewed-by: Daniel Dilan <danieldilan@google.com>

This PR is needed for parity with the existing PNG decoder in Blink / Chromium - see https://crbug.com/376550658.
IIUC Chromium and Blink only require an ability to decode these chunks - there is no need for encoding support (e.g. the search query here only finds decoder bits).
