03add801fe Improve unit tests for switch-case and enum error handling.
These tests verify that switches and enums only work with constant
integral values. Floats or uniforms should be rejected with an easy-to-
understand error message.

3e3db6c9a6 Make switch case handling safer
It's possible to construct a case value expression that's a compile time
constant, but fails to produce a value from getConstantInt. MSAN noticed
us using the uninitialized integer. It's now initialized, but also never
used in the failure case: We make getConstantInt return status, and give
better error messages in the two places it's used.

fe0de30a87 Enable ClangTidy check modernize-use-nullptr.
https://clang.llvm.org/extra/clang-tidy/checks/modernize-use-nullptr.html

The check converts the usage of null pointer constants (eg. NULL, 0) to
use the new C++11 nullptr keyword.

48bdf6ddb1 Use a scoped block for inlined return statements.
Inlined return statements emit two statements--an assignment, then a
break. If scope braces are otherwise missing, the break statement will
end up in the wrong place. i.e.:

Mistranslated:
	if (foo) return bar;  --> if (foo) out = bar; break;

Translated properly:
	if (foo) return bar;  --> if (foo) { out = bar; break; }

1cf2c8d6ec Enable ClangTidy flag modernize-use-override.
https://clang.llvm.org/extra/clang-tidy/checks/modernize-use-override.html

Adds override (introduced in C++11) to overridden virtual functions and
removes virtual from those functions as it is not required.

virtual on non base class implementations was used to help indicate to
the user that a function was virtual. C++ compilers did not use the
presence of this to signify an overridden function.

8c91c93dce Refuse to inline SkSL with returns inside breakable constructs.
We do not have a good mechanism to break out of a nested for/while loop
or switch statement. Our inlining approach generates incorrect code in
those cases, and there's no apparent fix, since we don't have a
mechanism for subverting control flow like 'goto'. When we detect this
case, disable inlining for that function.

dc3697036e Handle invalid DDLRecorder case
Prior to this CL, if we failed to create the DDL Recorder's target
proxy while creating the target surface we could create an invalid
DDL.

The specific repro case involved too big of an target proxy but
many other scenarios could result in the same behavior.

326b98981e Add platform image encoder for using NDK APIs
Bug: skia:10369

Add SkEncodeImageWithNDK, mirroring the CG and WIC versions, for
encoding with the NDK APIs added to R.

Rename SK_ENABLE_NDK_DECODING to SK_ENABLE_NDK_IMAGES and use it for
both encoding and decoding.

Move code for converting to/from NDK types into a common location.

Update encode_platform.cpp to use NDK encoding APIs when available and
to use both types of webp (lossy and lossless). Add tests specifically
for the new implementation.

Update NdkDecodeTest to use ToolUtils::equal_pixels for comparing
pixels.

776c2841f8 Move onDumpInfo calls in gencode to the private section.
`onXxxxx` methods in Skia generally appear to be non-public, which I did
not realize until after originally implementing this task.

Followup CLs will update the non-gencode `onDumpInfo` methods to be
private as well.

cab588677b Add GrProcessor::onDumpInfo for subclass info dumps.
This CL also marks `GrProcessor::dumpInfo` as final. This prevents a
subclass from mistakenly overriding `dumpInfo` instead of `onDumpInfo`.

`onDumpInfo` is responsible for providing the same data as `dumpInfo`,
except that the FP name is automatically prepended.

ba1879d9f1 Add dumpTreeInfo debug method to GrFragmentProcessor.
This is a net reduction in code size because this idea was already
implemented separately in two places:
- dump_fragment_processor_tree (GrProcessorSet)
- describe_fp (ProcessorTest)

This consolidates the implementations. This CL also fixes a handful of
dumpInfo() methods that were not sufficiently descriptive--e.g. the FP
name was missing, or the implementation was just buggy.

a4b9169fb6 Remove 'in' variables from SkRuntimeEffect
Runtime effects previously allowed two kinds of global input variables:
'in' variables could be bool, int, or float. 'uniform' could be float,
vector, or matrix. Uniform variables worked like you'd expect, but 'in'
variables were baked into the program statically. There was a large
amount of machinery to make this work, and it meant that 'in' variables
needed to have values before we could make decisions about program
caching, and before we could catch some errors. It was also essentially
syntactic sugar over the client just inserting the value into their SkSL
as a string. Finally: No one was using the feature.

To simplify the mental model, and make the API much more predictable,
this CL removes 'in' variables entirely. We no longer need to
"specialize" runtime effect programs, which means we can catch more
errors up front (those not detected until optimization). All of the API
that referred to "inputs" (the previous term that unified 'in' and
'uniform') now just refers to "uniforms".

87d0a2fa53 Update MakeChildFP to allow processor hierarchies to be created.
Previously, MakeChildFP avoided infinite recursion by rejecting any FP
that took inputs. MakeChildFP now generates random inputs up to a
user-supplied tree depth.

The ProcessorOptimizationValidationTest test has been updated to
test up to a tree depth of 3. The ProcessorCloneTest has been left at
a tree depth of 1 due to a bug that only appears on Galaxy S20/Mali G77.
The Mali bug doesn't appear to be related to FP cloning, but probably
deserves further analysis. (It appears that on this device, these
processors hooked together in sequence render a tiny bit differently
each time: DitherEffect -> RectBlurEffect -> ImprovedPerlinNoise. By
visual inspection it looks like the dither varies on each draw.)

ea8be2120e Update ProcessorClone test to re-verify problems without using clone().
Previously, this test would synthesize a random FP, call clone(), render
both, and the compare the results and report differences.

Now, if a difference is discovered, this test will re-synthesize the
originally-created random FP from scratch without using clone().
Instead, we call TestCreate again using the same random seed.
Then we can render and compare that output against the original as well.
This will allow to better differentiate failures that were actually
caused by clone(), versus failures caused by other types of
inconsistency.

If the regenerated version still mismatches, there are a variety of
potential explanations:
- the FP's TestCreate() does not always generate the same FP from a
  given seed
- the FP's Make() does not always generate the same FP when given the
  same inputs
- the FP itself generates inconsistent pixels (shader UB?)
- the driver has a bug

Finds local variable declarations that are initialized using the copy
constructor of a non-trivially-copyable type but it would suffice to
obtain a const reference.

The check is only applied if it is safe to replace the copy by a const
reference. This is the case when the variable is const qualified or when
it is only used as a const, i.e. only const methods or operators are
invoked on it, or it is used as const reference or value argument in
constructors or function calls.

ec9b4aab87 Enable ClangTidy check readability-const-return-type.
https://clang.llvm.org/extra/clang-tidy/checks/readability-const-return-type.html

`const` on a non-pointer/reference return type typically doesn't add
value and can have negative side effects. (i.e., returning a
`const std::string` isn't meaningfully different from returning a
`std::string`, but can sometimes inhibit move-related optimizations.)

In Skia's case, the priv() functions are a notable exception where const
return types are intentional and valuable. These calls have been marked
with NOLINT to exclude them from the check.

This check does not affect pointer and reference returns, where
constness is important.

fcf8cb2078 Implement matrix casting in Metal.
Unlike GLSL/SkSL, Metal does not natively support casting an array from
one size to another; we need to synthesize a helper function which will
assemble a new matrix from the values in the old matrix and the
identity.

Previously, our matrix-conversion helpers understood how to glom
together an arbitrary collection of scalars/vectors/matrices into a
matrix containing a matching number of scalars, but it would fail when
given a matrix of unequal size.
