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.

85bd4dff59 In SkImage::MakeFromEncoded, support overriding alpha type
Use that to preserve the alpha type of (unpremul) SkImages when
serializing. This ensures that the new GM works correctly in
serialize-8888, and is required for an upcoming "raw" image feature.

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).

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.

Add a getter to SkTypeface to provide information on whether it

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

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.

97284f255b [infra] Add initial platforms and constraint values
This makes use of Bazel's pre-defined platforms
https://github.com/bazelbuild/platforms
and some of our own defined values (see
//bazel/common_config_settings/BUILD.bazel) to customize
the build rules.

I verified this by building bazel_test locally for
linux x64 as well as using the third_party deps for
a WASM build (using build files not seen in this CL).

Suggested Review Order:
 - https://docs.bazel.build/versions/main/platforms.html if not
   already familiar with Bazel Platforms
 - third_party/BUILD.bazel to see that 1) all globs have
   been removed and 2) select() targets various
   platform constants or groups of constants to control
   sources, headers, and local_defines.
 - common_config_settings/ to see the groups of constraints
   created, as well as new constraint_settings defined
   (skdebug_impl)
 - supported_combinations/ to see how we can define supported
   sets of the constraint values (aka Bazel platforms).
   I imagine expanding this more, so we might have platforms
   named "linux_x64_emptyfontmgr_vulkan" or such.
 - //BUILD.bazel and bazel_test.cpp to see use of SkDebugf.
 - Everything else.

After this lands, oss-fuzz will be updated to set that
flag too. https://github.com/google/oss-fuzz/pull/6462

The change to SkTypes.h is to remove bit-rotted code that
prevents oss-fuzz from working.

8c75b2d30e Simplify conservative clip tracking for SkNoPixelsDevice
Deletes SkConservativeClip as a type, it was only used by
SkNoPixelsDevice at this point.

Simplifies the clip tracking to only rely on intersect/difference ops
(but also expands it to support updating overall bounds if the diff
op is a sufficiently large rectangle).

Adds SkRect::roundIn() -> SkIRect to match the exposed API for round()
and roundOut().

  227 |     rec->data()[len] = 0;

which is detecting that fBeginningOfData is a char and that this code
cannot be reached with len == 0. Work around this by changing
fBeginningOfData to be an array of one char containing the empty string
by default.

While making this change, also make fBeginningOfData and fRefCnt
private.

4979d2b18d Simplify device clip restriction impl
This removes all low-level handling of the device clip restriction. It's
no longer part of the SkDevice API, nor needed by any of the backend-
specific classes for handling their clip stack.s

The device restriction is intersected using a regular op when it's set
and it's remembered and manually applied to the device bounds when
resetClip() is called. This is all handled inside SkCanvas.

I also took the opportunity to add asserts and better state transitions
to its implementation, since it had been in an awkward middle ground
between depending on the save/restore stack and not being kept in
sync with it.
