6e74412a9c Create .gni files for samples, tests, gms, and benches.
Calling Python to find all these files is convenient, but error-prone.  It's easy to forget to call GN again when adding a file.  Each of these calls to Python also adds ~50ms to the run time of gn gen, which is small but adds up.

On my desktop, gn gen drops from 600ms to 150ms, noticeably faster.

This leaves one call to find.py for generating skia.h for fiddle.  We're not quite sure how to automate that process to happen entirely inside the :skia.h action while maintaining correct dependencies, so I'm leaving it for now.

19b91531e9 Add support for multiple frames in SkCodec
Add an interface to decode frames beyond the first in SkCodec, and
add an implementation for SkGifCodec.

Add getFrameData to SkCodec. This method reads ahead in the stream
to return a vector containing meta data about each frame in the image.
This is not required in order to decode frames beyond the first, but
it allows a client to learn extra information:
- how long the frame should be displayed
- whether a frame should be blended with a prior frame, allowing the
  client to provide the prior frame to speed up decoding

Add a new fields to SkCodec::Options:
- fFrameIndex
- fHasPriorFrame

The API is designed so that SkCodec never caches frames. If a
client wants a frame beyond the first, they specify the frame in
Options.fFrameIndex. If the client does not have the
frame's required frame (the frame that this frame must be blended on
top of) cached, they pass false for
Options.fHasPriorFrame. Unless the frame is
independent, the codec will then recursively decode all frames
necessary to decode fFrameIndex. If the client has the required frame
cached, they can put it in the dst they pass to the codec, and the
codec will only draw fFrameIndex onto it.

Replace SkGifCodec's scanline decoding support with progressive
decoding, and update the tests accordingly.

Implement new APIs in SkGifCodec. Instead of using gif_lib, use
GIFImageReader, imported from Chromium (along with its copyright
headers) with the following changes:
- SkGifCodec is now the client
- Replace blink types
- Combine GIFColorMap::buildTable and ::getTable into a method that
  creates and returns an SkColorTable
- Input comes from an SkStream, instead of a SegmentReader. Add
  SkStreamBuffer, which buffers the (potentially partial) stream in
  order to decode progressively.
  (FIXME: This requires copying data that previously was read directly
  from the SegmentReader. Does this hurt performance? If so, can we
  fix it?)
- Remove UMA code
- Instead of reporting screen width and height to the client, allow the
  client to query for it
- Fail earlier if the first frame AND screen have size of zero
- Compute required previous frame when adding a new one
- Move GIFParseQuery from GIFImageDecoder to GIFImageReader
- Allow parsing up to a specific frame (to skip parsing the rest of the
  stream if a client only wants the first frame)
- Compute whether the first frame has alpha and supports index 8, to
  create the SkImageInfo. This happens before reporting that the size
  has been decoded.

Add GIFImageDecoder::haveDecodedRow to SkGifCodec, imported from
Chromium (along with its copyright header), with the following changes:
- Add support for sampling
- Use the swizzler
- Keep track of the rows decoded
- Do *not* keep track of whether we've seen alpha

Remove SkCodec::kOutOfOrder_SkScanlineOrder, which was only used by GIF
scanline decoding.

Call onRewind even if there is no stream (SkGifCodec needs to clear its
decoded state so it will decode from the beginning).

Add a method to SkSwizzler to access the offset into the dst, taking
subsetting into account.

Add a GM that animates a GIF.
Add tests for the new APIs.

*** Behavior changes:
* Previously, we reported that an image with a subset frame and no transparent
index was opaque and used the background index (if present) to fill the
background. This is necessary in order to support index 8, but it does not
match viewers/browsers I have seen. Examples:
- Chromium and Gimp render the background transparent
- Firefox, Safari, Linux Image Viewer, Safari Preview clip to the frame (for
  a single frame image)
This CL matches Chromium's behavior and renders the background transparent.
This allows us to have consistent behavior across products and simplifies
the code (relative to what we would have to do to continue the old behavior
on Android). It also means that we will no longer support index 8 for some
GIFs.
* Stop checking for GIFSTAMP - all GIFs should be either 89a or 87a.
This matches Chromium. I suspect that bugs would have been reported if valid
GIFs started with "GIFVER" instead of "GIF89a" or "GIF87a" (but did not decode
in Chromium).

*** Future work not included in this CL:
* Move some checks out of haveDecodedRow, since they are the same for the
  entire frame e.g.
- intersecting the frameRect with the full image size
- whether there is a color table
* Change when we write transparent pixels
- In some cases, Chromium deemed this unnecessary, but I suspect it is slower
  than the fallback case. There will continue to be cases where we should
  *not* write them, but for e.g. the first pass where we have already
  cleared to transparent (which we may also be able to skip) writing the
  transparent pixels will not make anything incorrect.
* Report color type and alpha type per frame
- Depending on alpha values, disposal methods, frame rects, etc, subsequent
  frames may have different properties than the first.
* Skip copies of the encoded data
- We copy the encoded data in case the stream is one that cannot be rewound,
  so we can parse and then decode (possibly not immediately). For some input
  streams, this is unnecessary.
  - I was concerned this cause a performance regression, but on average the
    new code is faster than the old for the images I tested [1].
  - It may cause a performance regression for Chromium, though, where we can
    always move back in the stream, so this should be addressed.

d8765e3455 Define SK_CPU_SSE_LEVEL on Windows builds.
We check this define to know which intrinsics we can call safely.  The -msse flags set it for us on non-MSVC, but MSVC has no such switch.  We do this in GYP (and Chrome's GN) too.  No need for any defines on :avx or :hsw targets... the /arch:AVX and /arch:AVX2 do set SK_CPU_SSE_LEVEL for us.

Most directly, this means things like Sk4f::thenElse() will now use blendps when compiled into SkOpts_sse41.cpp.

78d5a3bac5 Add an SkOpts target for Haswell+ Intel chips.
Haswell brought a whole slew of handy new instructions for us (AVX2, FMA, BMI1+BMI2) and also feature F16C, which came one generation earlier on Ivybridge.  We work with integers often enough that we really want to target AVX2 instead of AVX, and this means it's pretty practical to ask for all those other goodies along with it.

Chrome's GN files and Google3's BUILD file will need an update, before or after this CL.

d68f9b0038 GN: ANGLE
Angle's existing GN files only work in Chrome, so I've written a new one.

This won't work on Windows, but our GN build doesn't work on Windows anyway.  So this CL is an attempt to get a ahead of that curve on ANGLE.  It looks large but fairly straightforward.

Now working on Linux:
  $ gn gen angle --args=skia_use_angle=true
  $ ninja -C angle
  $ angle/dm --config angle-gl --src gm -w dm-out

Request.h was missing an include for SkTypes.h, which supplies the default for SK_GPU_SUPPORTED if not otherwise defined.

38925aa37c Build tools on NoGPU bots.
I was just lazy disabling this before.  It turns out to not be difficult.

This gets us slightly better testing out of the NoGPU bot, as we now know
not only that Skia compiles, but also that DM and nanobench can link (and
thus that Skia's got enough compiled in it to be a coherent library).

skpbench requires GPU support.

4b5179b74c skpbench
skpbench is a benchmarking suite for skps that aims to generate 100%
repeatable results. The initial commit consists of three parts:

skpbench

A minimalist program whose sole purpose is to open an skp file,
benchmark it on a single config, and exit. No tiling, looping, or
other fanciness is used; it just draws the skp whole into a size-
matched render target and syncs the GPU after each draw.

Limiting the entire process to a single config/skp pair helps to keep
the results repeatable.

skpbench.py

A wrapper to execute the skpbench binary with various configs and skps.
It also monitors the output in order to filter out and re-run results
with an unacceptable stddev.

In the future this script will lock down and monitor clocks and
temperatures.

parseskpbench.py

A utility for parsing skpbench output into a spreadsheet.

6ef6999017 GN: Android Vulkan support
Android's the easiest place to start supporting Vulkan, so it's up first.

ndk_api becomes user-specifiable so that the Vulkan bots can kick it up
to 24, the first release supporting Vulkan.  The defaults remain the same:
18 for 32-bit and 21 for 64-bit, the first release supporting 64-bit.

To test this, I set ndk_api=24 and skia_use_vulkan=true in GN, then
   $ ninja -C out dm; and droid out/dm --config vk --src gm

Seems to work!  Bot scripts to follow.

cdedd0e061 Alternate approach to turn on freetype in Fuchsia.
What do you think of this?  It's basically what you wrote, factored differently.

Flipping on skia_use_freetype will enable the SkFontHost_Freetype*.cpp files
via the :typeface_freetype target.

Then we just pull out the SkFontMgr Fuchsia wants to use into its own little
:fontmgr_fuchsia target.  No major difference here, except the availability
of freetype headers, etc, is a bit more tightly scoped to just those that
need them.

We (obviously?) don't have Fuchsia builders, so I've got to rely on you for sanity testing this.

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.

c095df55e8 GN: guard tools (except fiddle) by skia_enable_tools.
Our tools use third-party libraries pretty freely, some of which may not
be available in other GN environments (e.g. Fuchsia).  Most can also not
function when Skia is built as a shared library.

fiddle stands alone as the exception to both those points: it depends on
only Skia, and works fine with both a shared or static library.

So guard everything but fiddle with this flag skia_enable_tools, disabled
when we're building for Fuchsia or when we're build a shared library.

This CL has a couple of little tweaks to Fiddle to keep it working:
  - divorce it from :tool_utils, instead just building SkForceLinking.cpp itself;
  - fix up a buggy rebase_path() that was accidentally working when we depended
    on :tool_utils;
  - drop test_only: it now only requires production-code dependencies.

The SkImageEncoder Create* methods need to be SK_API if we want SkForceLinking
to work across .so's.  Without this, SkForceLinking needs to be part of Skia; it
can't be part of the application using Skia.

The rest is mostly just a re-indent under if (skia_enable_tools),
courtesy of gn format.

eb3c425f1b GN: make libwebp an optional dependency
This will be handy for folks who don't have libwebp, like Fuchsia.

I convinced myself that this is done right by:
  - building in all three modes (default and explicitly set both ways);
  - looking at verbose Ninja logs to see the presence/lack of SK_HAS_WEBP_LIBRARY;
  - running dm -m Codec, which passes with libwebp and segfault without it.

If this is viable, I intend to make all third-party dependencies optional
and follow this pattern.  :skia should link and degrade gracefully without
any of //third_party.  It's okay for tools to have hard third-party
dependencies; we just need them to get past the `gn gen` stage without them.

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

  * Same sort of rename in Chrome's third_party
  * Aliased targets via //build/secondary in Chrome.

Are the GrGLCreateNativeInteface_* meant to be part of Skia-the-library

but we could easily move it to libskia if it's a thing we want to ship.

I'm honestly not sure I understand how this linked before without a definition
of GrGLCreateNativeInterface().  Or are there two, one real and one no-op
default with some sort of weak linking setup?  dlopen()?

ada5a44f3b GN: get echo-headers sources via exec_script
exec_script runs every time gn does, which is explicitly on every one of our
bot runs.  That should be enough to obviate the .git/logs/HEAD hack.

Easiest way to do this was to swap around find.py's argument order to allow
multiple search directories.  This is the root of all the .gyp changes.

This moves the blacklist into BUILD.gn, which I think is nice.
It expands it a little as we're now searching recursively, into include/gpu/vk
which we can't include safely without the Vulkan SDK.

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.

8796ff1fbc Turn on flags to enforce SK_API.
These flags hide symbols that are not marked with SK_API when linked into a
shared library.  There's nominally no effect on static linking, but I'm
pretty sure the Mac linker takes some advantage of this too to run faster.

This makes component-build DM no longer link: it uses many non SK_API APIs.
Fiddle in contrast is just fine with our public APIs, so no need to restrict that.

It'll be fun finding out which of our other tools go which ways.

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.

7d10b9f6e6 GN: fixes for Mac
- Make fiddle build on Mac (skipping GL).
 - Now that we're building in SkCodec, we depend on libpng and libjpeg-turbo unconditionally, not just on Linux.
 - Re-arrange third_party a bit so that our targets are Fuchsia/Chrome compatible.

This doesn't affect Chrome/Blink, so landing through the closed tree.

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.

I'll tell you what, I need to practice typing fuchsia out a few hundred
times...  I managed to spell it three different ways in this CL.

Plus, gn format BUILD.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.
