With this change, the CMake build, which does not use DEPS to sync external projects, is able to build and use the same version of libpng that is used in other builds. This will allow all platforms (including Google3 CMake build) to test on the same version of libpng, so we do not need to make SkPngCodec support all versions of libpng. - Update CMakeLists.txt to use the checked in libpng. - Check in libpng version 1.6.22rc01 - Update README.google - Replace our old LICENSE file with the latest one from libpng GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2033063003 CQ_EXTRA_TRYBOTS=client.skia.compile:Build-Ubuntu-GCC-x86_64-Release-CMake-Trybot,Build-Mac-Clang-x86_64-Release-CMake-Trybot Review-Url: https://codereview.chromium.org/2033063003

TRADEMARK:
|
|
|
|
The name "libpng" has not been registered by the Copyright owner
|
|
as a trademark in any jurisdiction. However, because libpng has
|
|
been distributed and maintained world-wide, continually since 1995,
|
|
the Copyright owner claims "common-law trademark protection" in any
|
|
jurisdiction where common-law trademark is recognized.
|
|
|
|
OSI CERTIFICATION:
|
|
|
|
Libpng is OSI Certified Open Source Software. OSI Certified Open Source is
|
|
a certification mark of the Open Source Initiative. OSI has not addressed
|
|
the additional disclaimers inserted at version 1.0.7.
|
|
|
|
EXPORT CONTROL:
|
|
|
|
The Copyright owner believes that the Export Control Classification
|
|
Number (ECCN) for libpng is EAR99, which means not subject to export
|
|
controls or International Traffic in Arms Regulations (ITAR) because
|
|
it is open source, publicly available software, that does not contain
|
|
any encryption software. See the EAR, paragraphs 734.3(b)(3) and
|
|
734.7(b).
