a343017fc2 Hide monobench target on debug builds.
Unlike nanobench this tool has no purpose when built in Debug mode.
Just don't let it happen.

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

ecbc526418 GN: build skiaserve
I trimmed the libmicrohttpd sources and defines down to the minimum needed to build and run.  This builds and runs on Linux and Android for me.

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

To build on Android, exit() -> _exit().

build.py was unused.

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.

Android API >= 24 implies Vulkan support, so we can have a more useful default here than 'false'.  If for some reason you wanted to turn it off, you can still override skia_use_vulkan.

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.

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.

650e20d705 SkPDF: Stop #include PREPROCESSOR_DEFINE pattern
No more:
   #include SK_SFNTLY_SUBSETTER
   #include ZLIB_INCLUDE

Also, rename SK_SFNTLY_SUBSETTER to SK_PDF_USE_SFNTLY
to follow my pattern of prefixing SkPDF-specific defines
with 'SK_PDF_'.

The ZLIB_INCLUDE define is no longer is used by anyone.

TODO: rename Sfntly to something pronounceable.

9b8583dd1f GN: misc
- Use options' template pattern for opts too.
  - Simplify opt's and options' configs... they should all be the same.
  - When building a static-library component in our GN environment (i.e. libskia.a),
    make it a complete static lib, fully containing its transitive deps.
  - It has not proved useful to override ar.

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.
