All platforms except android are configured to use the statically linked copy of libpng. Android uses the system provided dynamic copy for SkImageDecoder and the static copy for SkCodec. The exception being android framework builds that currently use the dynamic copy everywhere. This CL also enables NEON optimizations for libpng. Review URL: https://codereview.chromium.org/1058823002

Q: Why does this directory exist?
|
|
A: libpng is pulled in through DEPS, but in order to build it using ninja, we
|
|
need to create pnglibconf.h and pngprefix.h. We originally tried creating
|
|
the file as an action in https://codereview.chromium.org/930283002/, but this
|
|
apparently led to a race condition on Windows, where some builds failed to
|
|
create the file in time for other files to include it. By checking these
|
|
files directly into Skia, we eliminate the race condition.
