eae1848ec7 [graphite] Update two GMs that use local matrices
Graphite requires graphite images to be graphite-backed.

localmatrixshader_nested, in particular, is useful for ensuring
local matrices are handled correctly.

46eaab3959 [bazel] Add shims to help translation into G3
Ran the following commands:
find -name "BUILD.bazel" -exec sed -i -e '1iload("//bazel:macros.bzl", "cc_library", "exports_files_legacy")\nexports_files_legacy()' {} +
buildifier --lint=fix --mode=fix -r .

This had the effect of making sure we can export all of our
files in G3 (until we no longer have legacy targets) and
making all of our cc_libraries shim-able.

bazel/macros.bzl has the human-contributed changes, the rest
were mechanical.

a6eaac0595 Disable experimental HW tessellation
This should make it so the HW tessellation path renderers are never
used; it will always select the atlas or direct fixed-count renderers
instead. This CL will give us a good indication of what visual diffs
to expect, layout tests to rebase, and any performance regressions.

If those are acceptable, then we can proceed with the rest of the code
removal.

8499e372ce [includes] Remove more includes of SkColorSpace
While I was fixing up Chrome's uses, I found some failures
there that I did not see in Skia, and tracked them down
to a few other places where we include SkColorSpace
and it is not strictly necessary

 - SkCustomMesh.h
 - GrColorInfo.h
 - GrColorSpaceXform.h
 - SkColorSpaceXformSteps.h

For these files (and their .cpp files), I added enforcement
of include-what-you-use, and then fixed the myriad of places
which were depending on these transitive includes.

One change to help Chrome is the manual overloads of
SkImage::MakeFromAdoptedTexture instead of using default
parameters. This makes it so callers of that function
do not need to include SkColorSpace if they were going
to pass nullptr for it anyway.

5e8f45faf1 [includes] Prepare for moving SkColorSpace to forward declare
This updates all our callsites in preparation for removing
the #include "include/core/SkColorSpace.h" from SkImageInfo.h

According to go/chrome-includes [1], this will save ~150MB
(0.07%) from the compilation size. I think SkColorSpace is
a big include because it loads the skcms header, which is
big.

The follow-on CL will remove that link, once clients have
been updated as well.

08ece0c9a0 [includes] Enforce IWYU on sksl code
PS1 regenerates the Bazel files. Use it as the base change when
    comparing patchsets.

IWYU seems to do a good job of working with MyFile.cpp and
MyFile.h, but if there is just a MyHeader.h, it doesn't always
seem to throw errors if the includes aren't correct. This was
observed with include/sksl/DSL.h This might be due to the fact
that headers are not compiled on their own, so they are never
sent directly to the IWYU binary.

This change sets enforce_iwyu_on_package() on the all sksl
packages and then fixes the includes until all those checks
are happy. There were a few files that needed fixes outside
of the sksl folder. Examples include:
 - src/gpu/effects/GrConvexPolyEffect.cpp
 - tests/SkSLDSLTest.cpp

To really enforce this, we need to add a CI/CQ job that runs
bazel build //example:hello_world_gl --config=clang \
  --sandbox_base=/dev/shm --features skia_enforce_iwyu

If that failed, a dev could make the changes described in
the logs and/or run the command locally to see those
prescribed fixes.

I had to add several entries to toolchain/IWYU_mapping.imp
in order to fix some private includes and other atypical
choices. I tried adding a rule there to allow inclusion of
SkTypes.h to make sure defines like SK_SUPPORT_GPU, but
could not get it to work for all cases, so I deferred to
using the IWYU pragma: keep (e.g. SkSLPipelineStageCodeGenerator.h)

e253cc3e55 [bazel] Use toolchain features to opt files into being IWYU compliant.
PS1 regenerates the Bazel files.

It is recommended to review this CL with a diff from PS1.

Example output when a file does not pass the test:
    tools/sk_app/CommandSet.h should add these lines:
    #include "include/core/SkTypes.h"
    #include "include/private/SkTArray.h"
    #include "tools/skui/InputState.h"
    #include "tools/skui/Key.h"
    #include "tools/skui/ModifierKey.h"
    namespace sk_app { class Window; }

    tools/sk_app/CommandSet.h should remove these lines:
    - #include "tools/sk_app/Window.h"

    The full include-list for tools/sk_app/CommandSet.h:
    #include "include/core/SkString.h"
    #include "include/core/SkTypes.h"
    #include "include/private/SkTArray.h"
    #include "tools/skui/InputState.h"
    #include "tools/skui/Key.h"
    #include "tools/skui/ModifierKey.h"
    #include <functional>
    #include <vector>
    class SkCanvas;
    namespace sk_app { class Window; }
    ---

This makes use of Bazel's toolchain features
https://bazel.build/docs/cc-toolchain-config-reference#features
to allow us to configure compiler flags when compiling
individual files. This analysis is off by default, and can
be turned on with --features skia_enforce_iwyu. When enabled,
it will only be run for files that have opted in.
Example:
    bazelisk build //example:hello_world_gl --config=clang \
       --sandbox_base=/dev/shm --features skia_enforce_iwyu

There are two ways to opt files in:
 - Add enforce_iwyu = True to a generated_cc_atom rule
 - Add enforce_iwyu_on_package() to a BUILD.bazel file
   (which enforces IWYU for all rules in that file)

Note that Bazel does not propagate features to dependencies
or dependents, so trying to enable the feature on cc_library
or cc_executable targets will only impact any files listed in
srcs or hdrs, not deps. This may be counter-intuitive when
compared to things like defines.

IWYU supports a mapping file, which we supply to help properly
handle things system headers (//toolchain/IWYU_mapping.imp)

Suggested Review Order:
 - toolchain/build_toolchain.bzl to see how we get the IWYU
   binaries into the toolchain
 - toolchain/BUILD.bazel and toolchain/IWYU_mapping.imp
   to see how the mapping file is made available for
   all compile steps
 - toolchain/clang_toolchain_config.bzl, where we define the
   skia_enforce_iwyu feature to turn on any verification at
   all and skia_opt_file_into_iwyu to enable the check for
   specific files using a define.
 - toolchain/clang_trampoline.sh, which is the toolchain is
   configured to call instead of clang directly (see line 83
   of clang_toolchain_config.bzl). This bash script used to
   just forward all arguments directly onto clang. Now it
   inspects them and either calls clang directly (if
   it does not find the define in the arguments or we are
   linking [bazel sometimes links with clang instead of ld])
   or calls clang and then include-what-you-use. In all cases,
   the trampoline sends the arguments to clang and IWYU
   unchanged).
 - //tools/sk_app/... to see enforcement enabled (and fixed)
   for select files, as an example of that method.
 - //experimental/bazel_test/... to see enforcement enabled
   for all rules in a BUILD.bazel file.
 - all other files.

7ac7413f08 [bazel] Support Vulkan
PS1 regenerates BUILD.bazel files

I suggest reviewing the deltas between PS1 and the latest
PS to focus on the interesting bits.

The changes here allow for a Vulkan-only build of HelloWorld
based on sk_app. The toughest change was properly fetching
the VisualID after removing the gl calls that used to
fill that in.

There are a few changes that fix resolution of Dawn
header files, but those won't actually be built until
a follow-on CL.

b902658a1a [bazel] Fix Bazel build by guarding addToKey
PS1 is the automatic regenerated changes.
PS2-3 adds an #ifdef guard to the addToKey method on shaders.
The SkShaderCodeDictionary class helps generate SkSL and is
only necessary when we are building with SkSL (gpu builds and
cpu builds with SkVM).

Suggested Review order:
 - Use Gerrit to diff PS 1 and the last PS
 - src/core/BUILD.bazel adds some sources to the "only
   necessary if sksl is enabled" bucket
 - All the .cpp and .h files to see the #ifdef is added
   correctly.

9cb74e9079 [bazel] Compile gms for wasm and WebGL
PS 1 is re-generating existing BUILD.bazel files
PS 2 is generating BUILD.bazel files for tests/gms
PS 3+ makes modifications to build all of the gms and tests.

It is recommended to view this CL with just a diff between
PS 2 and the end, due to the large amount of generated changes
in PS 1 and 2.

We make a filegroup for the gms and tests because they need
to be compiled as one large blob in order for the registries
to work. Maybe in the future we will break these up, but at least
for WASM/JS, the overhead of starting a browser for each new
test would likely grind things to a halt, so we just group them
all together for now. It's also the most similar to what we
currently do.

In gm/BUILD.bazel and tests/BUILD.bazel, we add a cc_library
that encapsulates all of the deps of the tests, so we can
easily include that the build. These were discovered via
trial and error, not anything automatic or systematic.

The is_skia_dev_build config_setting is very similar to the
GN equivalent from which it was based.

The list of gms and tests to skip (e.g. which are incompatible
with WASM) was determined by building the wasm bundle:

modules/canvaskit$ make bazel_gms_release
tools/run-wasm-gm-tests$ make run_local_debug
# Don't forget to click the button on the screen after the
# browser loads

This way of invoking the tests will be replace soon with
`bazel test <something>`. As such, I didn't bother fully
documenting the current way.

Suggested review order:
 - modules/canvaskit/BUILD.bazel taking note that we always
   use profiling-funcs to make the stacktraces human readable.
 - gm/BUILD.bazel and tests/BUILD.bazel to see the lists of
   gms/tests. Notice the tests are roughly partitioned because
   we don't support things like vulkan/PDF in the wasm build
   and we will want a way to not build certain tests for
   certain configurations
 - tools/* noting some of the cc_libraries added to make
   dependencies easier to add when needed.
 - All other files.

1f8c31b101 [infra] Add initial Bazel rules and files
These rules can be used to build our GMs on WASM+WebGL and
libskia.a with just the CPU backend (and most other features
turned off).

This can be done with the following commands:
  - bazel build //modules/canvaskit:gm-bindings-wasm --gpu_backend=gl_backend --with_gl_standard=webgl_standard
  - bazel build :skia-core --config clang

This pivots slightly from http://review.skia.org/463517
by using config_settings [1] instead of platforms for
the optional features that we control. This pivot was
suggested in [2]

We have BUILD.bazel files in many of the subdirectories
that specify filegroups for the appropriate files. In
an effort to make //BUILD.bazel more readable, it is
the responsibility of these subfolders to deal with
conditionally including certain .h or .cpp files.
This is done using select statements and config_settings
or platform constraints as necessary.

For example, src/gpu/BUILD.bazel will different private
filegroups for each of the supported gpu backends [3]
and a more-visible filegroup called "srcs" that has
the right selection of the private files to be used
for compilation.

An effort has been made to avoid using glob() in our
BUILD.bazel files. These file lists were made by using
`ls -1` and some regex to add in quotes. We might want
to make a helper script to assist with that, if necessary.

To specify which options we have, the settings in
//bazel/common_config_settings/BUILD.bazel have been
redesigned. They make use of a macro `string_flag_with_values`
that removes the boilerplate. Patchset 36 shows what the
file looks like w/o the macro.

The top level BUILD.bazel file will still need to use
some logic to handle defines, because local_defines is
a list of strings, not a list of labels [4].

Suggested Review Order:
  - WORKSPACE.bazel to see the new dependencies on the
    emsdk toolchain and bazel_skylib
  - bazel/common_config_settings/* to see the few settings
    defined (we have more to define, see BUILD.gn and
    //gn/skia.gni for ideas)
  - BUILD.bazel to see the "skia-core" cc_library rule.
    See also "gms" and "tests"
  - modules/canvaskit/BUILD.bazel to see the use of
    the emscripten "wasm_cc_binary" rule, which depends
    on the "skia-core", "gms", and "tests" rule. Note that
    it only builds some of the gms as a proof of concept.
  - The other BUILD.bazel files. Some of these are not
    platform or feature dependent (e.g. pathops). Others
    are (e.g. gpu).
  - All other files.
