7d6fb2c92d GN: Android
Once you have downloaded an android NDK, you can set the ndk GN arg to use it.
E.g. my gn.args looks like:
  is_debug = false
  ndk = "/opt/android-ndk"

This should be enough to get you going for an arm64 build.  You ought to be able to tweak that to other architectures by changing target_cpu to "arm", "x86", "x86-64", etc.  That won't quite work until I follow this up a bit, but the skeleton is there.

This is enough to get me compiled, linked, and running to completion on my N5x.

0a8efd7355 GN: _turbo -> -turbo to match Fuchsia
We might as well match the folks who are using our GN files now.

We've got plenty of strategies in our pocket for when we try to move Chrome
onto our GN files (and who knows, there may be even a new better way by then):
  * Same sort of rename in Chrome's third_party
  * Aliased targets via //build/secondary in Chrome.
  * Indirection via build_overrides

2b6870ccb2 GN: nanobench
Add nanobench, and while we're at it monobench to show off how cool
source_sets are... the bench files are only built once then linked
into both binaries.  With GYP we build them twice. :/  Same deal
for GMs between nanobench and DM... build once, link twice.

nanobench uses SkImageEncoder to encode its .pngs, which requires
we link in the image encoders, which requires we get them all in.
That's the bulk of this.

0634317cbe GN: fix mac build again
Hoping to land these using the other GN bots as trybots.

Don't know what magic was letting us get to webp's headers yesterday on Linux.  Might have been using /usr/include's ?

The other change is the difference between some setups using #define SK_BUILD_FOR_MAC and others #define SK_BUILD_FOR_MAC 1.  We want either to mean "we're Mac".

25c81d4e65 GN: dm
This builds, links, and runs on Linux.  Have not tried Mac.

I've tested is_debug={true,false} and is_component_build.
It's neat that the component build DM works, but it's also an indication I've missed an essential flag or two... it shouldn't work. :)

The GPU backend isn't working yet, but all the software configurations I've tried look good.

This fleshes out all the other parts of SkCodec too... I noticed we weren't able to decode gifs or webp.

7fbfbbe8f4 Basic standalone GN configs.
This sketches out what a world without Chrome's GN configs would look like.

Instead of DEPSing in build/, we now host our own gypi_to_gn.py.

The symlink from skia/ to . lets us run gclient hooks when the .gclient file is in the directory above skia/ or inside skia/.  That means we don't need gn.py anymore.

f037d48e29 GN: refactor third_party/gni
This fixes the build on Linux (dep on third_party:zlib -> third_party/zlib).

  I've moved declare_args() {} back to each .gn file... seems like args want
  to be as local as possible in GN land.

  Additionally, refactor all the common third_party config and warning flag
  changes into a template, third_party.  This lets it all live together in a
  .gni: at head unwanted_configs can be in a .gni (it's just a variable) but
  config("no_warnings") (and thus third_party_configs) cannot, as configs
  cannot be part of .gni files.

c04ff4788c GN
What we've got here is a little GN MVP.  It's lacking any knobs and doesn't yet build anything but libskia, zlib, libpng, and libjpeg-turbo.  I've been hopping back and forth between Linux at work and Mac at home.  These seem to be at least partially working, enough to build and run cmake/example.cpp.

The xcode backend seems to work.  From here, we can start exploring how to handle other backends (cmake,Android make, Google3).  There are a couple things I want to try:
  - add another backend like vs or xcode to GN directly
  - intercept via a custom toolchain
  - reverse from ninja -t commands
That last option seems kind of fun.

This tries to piggyback on Chrome's GN setup as much as possible.  Chrome's got quite a lot figured out, and we're basically required to do this if we want to have a single GN build system shareable by Chrome, our bots, and other clients.

This pulls in some new DEPS:
   - build: Chrome's GN configuration, and much more
   - buildtools: hashes for gn binary, pulled via hooks
   - tools/clang: hashes for Chrome's clang, pulled via hooks into third_party/llvm-build
It additionally symlinks tools/gyp to third_party/externals/gyp.  GN pulls some stuff from tools/gyp on Mac.

Have not yet tried building for Windows, Android, or iOS.

51190df040 Add SkDrawPosTextHCommand JSON, fix skiaserve build.
Adds SkDrawPosTextHCommand ::fromJSON and ::toJSON.

Both SkDrawPosTextCommand and SkDrawPosTextHCommand's
::toJSON write the correct number of positions, preventing reading
uninitialized memory.

The microhttpd build is now done in the build tree as opposed to in a
temporary directory.

The microhttpd build script uses os.path.join so that absolute paths
do not confuse the build. This allows compatibility with the cmake
gyp generator as CMake likes to pass absolute paths.

The microhttpd gyp target is now marked as 'none' since it is not
a 'static_library' target (which directs gyp to compile sources into
a static library). The dependencies to the action are updated to the
minimum required for sane re-building.

The everything gyp target now depends on the skiaserve gyp target.
This means that when using skia_build_server=1, building 'most' will
build skiaserve, but when skia_build_server is not defined the
skiaserve target will still be available if specified manually.

The old json.gyp is removed as it currently does not build anything.
All of the files currently referenced by it as sources no longer exist.

740668d907 Update libpng to 1.6.22beta
Intel SSE filter optimizations have been upstreamed.  Let's test on
the upstream version (which we can use in Android).

77b798ce8e Update the version of libpng used by Skia tests
The version of libpng we were using has some security vulnerabilities.
Update to a newer version - 1.6.20 (047737496a/).

Update pnglibconf.h. The new version is a copy of the newer version of
the file, with our /* custom settings */ tacked onto the end. (The
custom settings are unchanged from the last version.)

Update the LICENSE. The new version is a copy of the LICENSE that
libpng now includes as a separate file.

Update the README file to reflect the change in source of the LICENSE
file.

372d65cc6e sketch hooking into PNG_FILTER_OPTIMIZATIONS
Local timing says this 4-byte Paeth function takes about 0.3x the time the serial libpng code does, dropping from ~10 cycles per byte to ~2.9.

bpp=4 is mainly an easy demo.  This approach can work for any bpp up to 16, 1 pixel at a time, at roughly the same cost per pixel.  Doing more than 1 pixel at a time is a tricky math problem I have yet to attempt to solve.

Everything here can be trivially downgraded to MMX, supporting bpp up to 8.  It seems to be a little slower (~3.5 cycles per byte), but it would make the code compatible with every x86 that can still power on.

I've tried four approaches:
  - this way;
  - doing things naively in 16-bit;
  - a 16-bit version that requires division by 3 (i.e. mulhi_epu16(..., 0x5580) );
  - a mostly 8-bit version of the same.

They're all fine, but this one is consistently the fastest I've measured.
I'd be happy to settle on the naive 16-bit version too, which would have a very clear implementation that's only minorly slower than this version.  The other two are way more complicated, and would require us to draw some serious ASCII diagrams to explain.

I have learned that the .skp serialization tests (serialize-8888) have a nice side effect of testing the correctness of these filters!

(Since writing the description above, I've bumped things up to {Paeth,Sub,Avg} x { 3 bpp, 4 bpp }.)
