dfc7f31bd1 Create a public base class for debug traces.
SkRuntimeEffect needs an API for generating debug traces. This means
that we will need references to debug traces inside a public header.
Rather than reference SkVMDebugInfo directly, we now have a simpler
base class for debug traces. This is better suited to landing in
include/.

I've also renamed SkVMDebugInfo to SkVMDebugTrace for consistency, since
it now contains all the trace data. (When it was first added, it only
had the slot info.)

20c6a947af Add SkImage::makeRawShader
This creates SkImageShader instances that do not perform color space
conversion, nor do they premultiply their pixels (if they started out
unpremultiplied). These are useful for runtime shaders that want
non-color inputs (like normal maps or lookup tables).

Includes GM that demonstrates lack of color conversion, and lack of
premultiplication in the context of a lighting shader.

4bd08c52c0 [infra] Add SkParagraph (harfbuzz, ICU) to Canvaskit Bazel build.
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.

6ba9f702ba [bazel] Try adding cc_binary rules that use generated rules
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.html
https://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.

00aa1a9259 Prevent 'binding' and 'set' on struct/interface block fields
I should have realized the fuzzer would find this assert when I added
it. Now the front-end rejects these layout qualifiers on both struct
fields and interface block fields. LayoutInInterfaceBlock.sksl is a
reformatted version of the fuzzer input. LayoutInStruct is hand-crafted
to trigger the same failure on a different code path. Both would
previously assert in the SPIRV generator. Now, neither one gets that
far.

9488e0237d [infra] Experiment generating BUILD.bazel files
This uses the gazelle extension from
https://skia-review.googlesource.com/c/buildbot/+/473357

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).

33fb008669 Add parser support for u suffix on literals.
Because SkSL is much more permissive than GLSL about literal types, we
don't actually need to treat values any differently when the `u` suffix
is added. That is, `uint x = 4000000000;` already worked fine. When we
encounter the `u`, we just ignore it. This also means that a literal
like `-100u` would be accepted without complaint (although you'd get a
range error if you tried `uint x = -100u;`).

The value-add here is that it removes a speed bump when porting GLSL
code to SkSL. The Filament example shader used the `u` suffix anywhere
that bitwise ops were present; finding and removing all of them was a
chore.

Also of note: the `u` suffix was only added to GLSL in ES3, but we
"support" it everywhere. (We could go out of our way to detect it in
ES2 and flag an error, but that benefits no one.)

8ed49ea6e3 [infra] Add Bazel rules for codecs.
This ports the third_party BUILD.gn files related to codecs
(with a best-effort on arm/SIMD stuff). This includes:
 - libpng
 - libjpeg-turbo
 - libwebp
 - wuffs (gif)
 - libgifcodec
 - dng_sdk and piex (raw codec)

This expands the string_flag_with_values macro to allow
multiple values to be set at once. This was added in Bazel 5.0.0,
however the latest pre-release version of that has a bug [1]
which slows down compilation dramatically. This was fixed at
ToT, but not released. As a result, I started using the Bazel
6 pre-release (via bazelisk).

The macro select_multi makes writing select() where multiple
elements could be on possible/easier.

One can try compiling certain codecs by running:
bazel build :skia-core --config clang --include_codec=raw_codec --include_codec=png_codec

Suggested Review Order:
 - bazel/macros.bzl
 - bazel/common_config_settings/defs.bzl and its BUILD.bazel
   to see how the codec options are defined.
 - BUILD.bazel to see how the codec settings are used.
 - src/codec/BUILD.bazel to see the inclusion of Skia files to
   deal with specific codecs.
 - third_party/BUILD.bazel (while referencing the corresponding
   BUILD.gn files, such as third_party/libwebp/BUILD.gn)
 - Everything else.

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.

7cde28909f Enforce basic limits on function stack size in SkSL.
Functions that declare variables totaling more than 100,000 slots will
now generate an error.

This is only a partial mitigation to the problem, as a sophisticated
attack could still chain/nest multiple functions together to consume
extremely large amounts of stack. However, this mitigation is still more
sophisticated than our peers; both WebGL and glslang are susceptible to
similar problems, and in the general case (ES3+ with full flow control)
it's intractable.

Add a getter to SkTypeface to provide information on whether it

strike cache can determine caching requirements.

Since remote SkTypefaces do not have access to table information,
implement this as a serializable flag, with font-blob backed
implementations being able to return this based on whether they
have a COLR table or not, starting with FreeType.

GR_MAKE_BITFIELD_OPS and GR_DECL_BITFIELD_OPS_FRIENDS
renamed to SK_* and moved to private/SkMacros.h

This avoids our public includes using a src header file
and messing with SkUtils.h, which apparently was used
by Android. That should be cleaned up in a separate effort.

4b38d9c437 Reland "Avoid crash when surface CoW allocation fails"
On low memory machines a common cause of crashes is when a draw
operation requires a large layer (or many large layers) because an
implementation of SkSurface_Base::onCopyOnWrite does not actually have
the resources available to do the copy when required by a draw. Allow
this method to fail and percolate up the call chain so that the draw
simply does not happen instead of crashing.

It appears some users are creating their own subclasses of
SkSurface_Base for their tests. Add SK_SURFACE_COPY_ON_WRITE_CRASHES to
keep the old crashy behavior until they can be updated.
