83dae92318 Remove SkSL sample-with-matrix implementation
Simplifies SampleUsage quite a bit (no need to track multiple kinds of
sampling, variable matrices don't exist any more, etc...).

577c6067a1 Runtime effects: Support input color as a parameter to main()
For now, just bolt this onto the existing runtime effects. The next step
is to add dedicated modes to the compiler for shader vs. color filter.
Once we get there, we will be much more strict about main signature in
each mode (and start adding other per-mode error checking).

9d26af9a82 Fix testing of Runtime Effects with inlining enabled and disabled.
Previously, the act of painting a Runtime Effect was causing its helper
functions to get inlined, even if inlining was disabled during the
initial SkSL generation. This meant that the "NoInline" path was not
actually very effective.

dbd4e6f0c0 Move ProgramKind and ProgramSettings types out of SkSL::Program.
This change will allow these types to be forward-declared; C++ doesn't
allow forward declaration of types declared inside a struct. Moving
these types out of Programs resulted in a large diff.

The Settings::Value helper class has been moved inside of the
IRGenerator. In practice, it was actually just an implementation detail
of how IRGenerator looks up caps-values by name. It seems very unlikely
that this will be necessary elsewhere going forward.

55761ae5e6 Change pipeline stage callbacks to support mangling type names
Structs, enums, and global variables are all going to require name
mangling. Move that to a separate virtual on the callback. More
importantly, the generator is going to need to do type-name substitution
inside the function declaration string, so the contract has shifted:
The generator constructs the entire function declaration line (using the
mangled name it gets from the new callback), then it calls
defineFunction with two strings, and a flag indicating if this is main
or not.

690b6f3a92 Remove PipelineStageArgs and format-string handshake
There is now PipelineStage::ConvertProgram, which takes a collection of
callbacks, and processes an entire program. For program objects that may
need name mangling, the callbacks return the new name, which is recorded
and used for future references to that object (eg uniforms & functions).

The callbacks let the FP inject new elements programmatically:
  - Declare uniforms and get handles
  - Emit child functions
  - Invoke child processors for calls to sample()

In a follow-up CL, we can add an skslc `.rte -> .sksl` mode, where the
callbacks just emit the description() of the relevant element. We can
also follow the same pattern to emit declarations of types (structs,
enums), and global variables.

236ddb3e1d Detach pipeline-stage generator from SkSL compiler
This is now structured like the VM generator: Just a function that does
the conversion. Moved all relevant types and constants out of the
compiler, too. The key thing is that we don't need/want an error
handler, because it's too late to fail. We *must* catch all errors
during IR generation.

This is also another step along the path of directly emitting to the
fragment shader builder, rather than generating strings with
placeholders.

20e92f77e2 Update SkRuntimeEffect::Make to take an Options struct.
This allows us to control the inline threshold of runtime effects in a
thread-safe way.

The new Make API now returns a struct, for readability; the old Make API
continues to return a tuple.

The old Make function is deprecated and subject to removal. You can
migrate to the new API by passing a default-constructed Options struct.
In this case there will be no difference in behavior.

d7e7659cad Move GrShaderCaps from Program::Settings to Compiler
This ties the caps to the compiler instance, paving the way for
pre-optimizing the shared code. Most of the time, the compiler is
created and owned the GPU instance, so this is fine. For runtime
effects, we now use the shared (device-agnostic) compiler instance
for the first compile, even on GPU. It's configured with caps that
apply no workarounds. We pass the user's SkSL to the backend as
cleanly as possible, and then apply any workarounds once it's part
of the full program.

d6cf56fd34 Revert "[svg] Relocate out of experimental"
This reverts commit 6fc4106a9d.

Reason for revert: Blocking the Android roll

Original change's description:
> [svg] Relocate out of experimental
>
> Move the SVG rendering code to modules/svg, and componentize.
> Also split into include/src/utils.
>
> As external clients still reference the old header locations,
> introduce temporary forwarding headers to facilitate the migration.

7d0f853158 Add SkImageFilters::Shader in place of Paint factory
SkImageFilters::Paint did not use every slot of the SkPaint, with only
its color, alpha, color filter, and shader having a meaningful effect on
the image filter result. It was always blended into a transparent dst,
so blend mode wasn't very relevant, and it was always filled to whatever
required geometry, so stroke style, path effect, and mask filters were
ignored or not well specified.

Color, alpha, and color filter can all be combined into an SkShader, so
a more constrained SkImageFilters::Shader provides the same useful
capabilities without as many surprises.

SkImageFilters::Paint still exists, but is deprecated to be removed
once I've confirmed clients aren't depending on it.

493f89e577 [fuzz] Standardize, document, and backport fuzzing defines.
We had several defines around the code base that were not
very descriptive. Additionally, we had a patch of extra
runtime restrictions living in oss-fuzz that were applied
when fuzzing over there for some fuzzers.

This has all be consolidated and controlled via the defines
documented in site/dev/testing/fuzz.md

As such, we can remove one of the patches that is in oss-fuzz,
taking us closer to being able to fuzz in the CI/CQ.

PS 1 renames existing fuzz defines to the new schema.
PS 2-3 backports skia.diff from oss-fuzz and changes those
definitions to have the _GREATLY modifier.
PS 5+ further condenses the defines so that there is one
define for gating the runtime checks.

bcfc554fde Add GrDirectContext arg to SkImage::readPixels
Note: The polarity of the staging flag is inverted from usual because
a G3 dependency with no SkUserConfig.h relies on the legacy API.

Once this lands, we will migrate them and others, then remove the
staging API. The inverted staging flag is kind of nice, actually - I may
use that pattern in the future. It means less total CLs and it's just as
easy to flip the bit on or off during debugging.

a008b0fa8b Enable ClangTidy check readability-redundant-smartptr-get.
To my surprise, this even works with homegrown smart pointers (such as
SkTLazy).

https://clang.llvm.org/extra/clang-tidy/checks/readability-redundant-smartptr-get.html

Find and remove redundant calls to smart pointer’s .get() method.

Examples:

  ptr.get()->Foo()  ==>  ptr->Foo()
  *ptr.get()  ==>  *ptr
  *ptr->get()  ==>  **ptr
  if (ptr.get() == nullptr) ... => if (ptr == nullptr) ...

de7d927db3 Reland "Add inline threshold to SkSL::Program::Settings"
Keep the same default value, but add a (private) API to change it when

Use the new API to improve fuzzer coverage, by fuzzing with inlining
disabled and (enthusiastically) enabled.

This reverts commit 3e8fae7193, reworked
to avoid the static initializer.
