When the layer type is missing, fType == -1 and we rely on unsigned
(size_t) underflow + check against the known types array size to catch
the condition.
The problem is SkToSizeT() itself asserts the input is a valid size_t,
and even if it didn't clusterfuzz would likely complain about
underflowing.
Refactor to check for negative values explicitly.

The issue was Skia would be in the middle of drawing when it
needed to lazy-load the image's texture. This would mess up the
bound texture in WebGL, but Skia didn't know that. As a result,
it would not realize that some of the work had been undone.
Calling resetContext() makes Skia aware of this fact, so it can
adjust its behavior.

There was only one virtual method, so switch that to a bool stored in

easy way to adjust how the new localToDevice is constructed.
With this change, we don't need SkSimpleMatrixProvider. SkMatrixProvider
is concrete, so we can use it directly. SkOverrideDeviceMatrixProvider
no longer needs the original provider for anything, so remove that
parameter. It now exists solely to inhibit the hitsPixelCenters flag.
Fix a few spots (SkParticleBinding, some sites in SkRuntimeEffect) where
we used SkSimpleMatrixProvider, even though the local coordinates being
passed did not obey the hits-pixel-centers constraints.
Most importantly, document how localToDeviceHitsPixelCenters works.

As a follow-up to https://skia-review.googlesource.com/c/skia/+/476219,
this sketches out how we can maybe use cc_library for the things
in //modules to make sure something in //src doesn't depend on
anything in //modules, for example.
The following succeeds:
bazel build //modules/skparagraph:skparagraph --config=clang \
--shaper_backend=harfbuzz_shaper --with_icu
As does `make bazel_canvaskit_debug` in //modules/canvaskit
Suggested Review Order:
- third_party/BUILD.bazel for ICU and harfbuzz rules. Pay
special attention to the genrules used to call the python
script for turning the icu .dat file into .S or .cpp.
- bazelrc and bazel/ for new flags and defines that control
use of ICU and harfbuzz. Unlike GN, with the public_defines
that get added in automatically if icu or harfbuzz is
depended upon, we need to set the defines at the top level.
This necessity might go away if we change the atoms to
depend on //modules/skshaper, which could define that flag.
- Top level BUILD.bazel files in //modules/skparagraph,
//modules/skshaper, //modules/skunicode, //modules/canvaskit

To make the atomic rules a bit easier to work with, in many
of the folders, this adds in cc_library rules to group
together the sources from that folder (and subfolders
where prudent). We only needs sources because those atoms
should have their headers as deps.
One issue that was pointed out is that there is currently
no way to restrict the inclusion of certain packages,
a la, `gn check`. For example, there is no mechanism from
stopping a dev from adding
#include "modules/canvaskit/WasmCommon.h"
to something in //src/core (except circular dependencies).
We can probably address that using Bazel's visibility
rules as needed:
https://docs.bazel.build/versions/main/visibility.htmlhttps://docs.bazel.build/versions/main/be/functions.html#package_group
It is recommended to look at this CL patchset by patchset.
PS1: Update gazelle command to generate rules in more folders.
PS2: A few changes to make generation work better.
PS3: The result of running make generate in //bazel
PS4: Adding the rules to build sksllex, the simplest binary I
could find in the Skia repo.
PS5: Adding the rules to build skdiff, a more complex binary.
I tried a few approaches, but ended up gravitating back
towards the layout where we have each folder/package
group up the sources. I imagine at some point, we'll have
skdiff depend on skia_core or something, which will
have things like //src/core, //src/codecs, //src/pathops
all bundled together.
PS7: Added in the groupings of sources, similar to what we had
earlier. I liked these for readability. These helped fix
up the //:skia_core build, and by extension, the CanvasKit
build.

- Spot check one or two of the BUILD.bazel files.
This CL generates the "atomic" rules for src/, include/ and

`bazel build --config clang //include/...` works
`bazel build --config clang //src/...` starts compiling,
(which verifies that the BUILD.bazel files are all valid),
but runs into errors because not all third_party deps have
been resolved, and there are some files missing from the
toolchain still (e.g. EGL headers).

BUILD files, i.e. one rule "srcs" that brings in the necessary

To work around an abort with LLVM [1], we have to go back to an
earlier version of emscripten (temporarily?).
Future work should look at using transitions [2] to allow various
executables (e.g. CanvasKit, DM) to set their own set of Bazel
flags, w/o the build invokers having to specify them.
These transitions might be able to handle more complex cases
that we currently use if statements in GN to deal with.

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"

on the "skia-core", "gms", and "tests" rule. Note that

`a || b` only evaluates b if a is false. `a | b` always evaluates
both a and b. If a and b are of type bool, `||` is usually what you
want, so clang now warns on `|` where both arguments are of type bool.
In Skia, 3 of 3 uses of `|` were intentional as far as I can tell (one
had an explicit comment, the other two didn't). Rewrite them slightly
to make this intent more clear and to suppress the warning.
There was also one use of `&`. That one looks like a (benign) typo for
`&&`, so change it.

Classes of issues addressed:
1. static constexpr class variables aren't automatically inline. Already handled in a separate CL
2. Lack of C++17 copy elision means classes of objects constructed at function return need a copy or move constructor even if RVO will mean it isn't called.
3. Nested braced init no longer allowed for base classes of subclasses without constructors.
4. template static constexpr var in template class throws error about redundant initialization. Adding inline and removing defn outside of class fixes it.
5. Some places that should have been including std headers now actually need to include them.
6. No auto template parameters.
7. No lambdas in constexpr funcs.

This is in prep for compiling with -std=c++14 and -Wno-c++17-extensions
when building with clang. Chrome has encountered problems with
third_party headers that are included both in Skia and other Chrome
sources that produce different code based on whether preprocessor macros
indicate a C++14 or C++17 compilation.
In C++17 they are already inline implicitly. When compiling with C++14
we can get linker errors unless they're explicitly inlined or defined
outside the class. With -Wno-c++17-extensions we can explicitly inline
them in the C++14 build because the warning that would be generated
about using a C++17 language extension is suppressed.
We cannot do this in public headers because we support compiling with
C++14 without suppressing the C++17 language extension warnings.

In addition to single line (point) text, AE also supports path layout
for paragraph text.
At a high level, the paragraph box top is mapped to the path (following
alignment rules), and each glyph is displaced along its path positioning
vector, post orientation.
The main difference compared to point text, is that the distance on path
is based on the fragment position relative to the paragraph left edge.
The paragraph box also plays a role in alignment: left/center/right
aligns with path start/mid/end.
This includes a tangential optimization: instead of validating cached
contour data in each PathInfo::getMatrix() call, we only check once at
a higher level (onSync) -- to avoid performing a shape vector comparison
for each fragment.

The Fill effect has separate "color" and "opacity" components.
In AE, the color chooser does not allow modifying the alpha channel --
the only source for Fill transparency is the opacity property.
Thus, the alpha component of the color property should always be 1.
But in practice, it appears Bodymovin sometimes exports the color with a
zero alpha field (BM always encodes colors as 4-float arrays).
To workaround this issue, update Fill to ignore the color alpha and only
use the explicit opacity.

Turns out AE's saturation is more sophisticated, both in implementation
and in control mapping.
Updating the effect to use a chain of specialized color filters:
- keep HSLAMatrix() for hue adjustments
- introduce a custom runtime effect for saturation
(following AE's semantics)
- use a plain Matrix() CF for lightness adjustments
