The client passes a GrDirectContext* when creating a vertex or index
buffer. The data is copied to a GPU accessible buffer object
and the client gets a Skia object that may only be used with the GrDirectContext. The GPU backend draws directly from the buffer, thereby
avoiding the per-draw copy cost.
The underlying Ganesh object is freed in a thread-safe manner using an
existing message bus to perform a delayed unref in GrResourceCache.

SkCustomMesh is a class with factory functions. Vertex and index
data are stored in buffer objects rather than raw pointers. User can
provide offsets into the buffers.
Currently the buffers are always CPU backend and are uploaded to the
GPU on each draw. However, buffer the creation API takes a
GrDirectContext which in the future will be used to create a GPU-backed
buffer specific to the passed context.

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.

The implementation is inconsistent across CPU and GPU.
CPU currently always implements kStrict even when kFast is passed.
For mipmapping this means computing a set of levels from the subset,
which is an expensive.
GPU limits the texture sampling coordinates to the subset in the
base level. However, higher level mipmap pixels that map back to
a footprint outside the subset are still sampled. So GPU pays a
higher shader complexity cost without really providing the benefit
of kStrict.
We are adding anisotropic filtering, which will not work well with
kStrict, and thus will also be disabled by kStrict.

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)

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.
