SkRuntimeEffect::MakeForXxxxx compiles its shaders before MakeTraced()
is invoked, with optimizations enabled. When MakeTraced() is called,
we recompile the shader with optimizations disabled; this allows us to
present the user with a shader that is as close to the original as
possible. (This obviously costs time, but debug trace generation isn't
focused on speed.)
Note that in some rare instances, disabling optimizations can cause
compilation to fail (e.g. optimization can simplify control flow and
eliminate "unreachable" paths). In those cases, we fall back to the
existing behavior of debugging an optimized shader.

Added comments to explain the semantics (both what's expected when you
set the uniform, and what you see in the shader). The old name was
confusing, because it sounded like you got an sRGB color in the shader.
This is terse, but I think it's the cleanest syntax - and for embedding
clients, they can use C++ (etc.) API to require that color uniforms are
assigned from color types.

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
- All other .bazel file changes are automatic.

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.

Review Tips:
- Ignore any changes to .h or .cpp files. Those have been
pulled out into their own CLs.
- Start with bazel/macros.bzl.
- Read the CL with the generation code, if you haven't already.
- Look at third_party/file_map_for_bazel.json.
- See experimental/bazel_test for an idea of how a cc_binary
would be made.
- Spot check one or two of the BUILD.bazel files.
This CL generates the "atomic" rules for src/, include/ and
modules/skshaper, as a starting point.
`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).

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.

Runtime shaders, color filters, and blenders are all able to sample from
a blender. These use the blend-function signature; both a src-color and
dst-color must be passed to sample. i.e.: sample(blender, s, d)

The preexisting enum versions now are just shallow factories for
the new blender versions, though internally we've kept the
specializations on impl.

fChildren in the Builder is now a vector of ChildPtrs instead of a
vector of one particular type of child. This gives builder.child() the
flexibility to accept a color-filter, shader, or any other type that a
ChildPtr can hold.

It's still accessible internally (and by default when using
SkMakeRuntimeEffect), but we don't want clients using this.
If we can come up with a simple and consistent coordinate
model that doesn't expose implementation details, we'll
revisit this.

... to aid in removing special ArithmeticImageFilter.
Can we use something like this to reimpl the ArithmeticImageFilter
--> BlenderImageFilter?
I see some special checking in filterBounds for ArithIF -- is that
required? Is that generalizable for any BlenderImageFilter?
If we can generalize blend[er]imagefilter, let's just move this
logic into Chrome -- no need for Arithmetic to appear in Skia
in any form!

We still need *a* copy, to satisfy SkSL that mutates the input color
parameter, but it almost never needs to be global, unless there are
calls to sample() from a function other than main.
With that tweak, we generate much better SkSL/GLSL code from every one
of our effects, avoiding the proliferation of global variables.
