80d2a50d4b Move newly-updated variables to the top of the Variable list.
Previously, the variable pane listed variables in slot order, which was
not very helpful (other than usually mapping to a top-to-bottom order in
the original source code). Now, the variable pane sorts variables to the
top when they are modified, and maintains their relative order
throughout execution. This is much easier to follow.

Reason for revert: ends up not being useful after all

Original change's description:
> Trace function return values after function-exit.
>
> This will allow function return values to be easily seen when stepping
> "over." This has the unexpected side benefit of generating slightly
> fewer ops when a function has unoptimizable conditional returns.

15f186d277 GrMemoryPool always standard_layout for offsetof
GrMemoryPool in debug has extra fields and so wants to make use of
offsetof. The offsetof can only be taken on standard layout objects.
However, in debug std::unique_ptr may not be standard layout, which
makes SkAutoTArray not standard layout, which makes SkTHashTable not
standard layout, which makes SkTHashSet not standard layout, which makes
GrMemoryPool not standard layout, producing a compile error.

Since this is debug only, move the debug only fields behind a pointer
(which unfortunately cannot be a std::unique_ptr, since it may not be
standard layout). This allows building with recent libc++ headers and
clang.

3695bdb587 Refactor SkMatrixProvider slightly
There was only one virtual method, so switch that to a bool stored in
the base class. The derived types exist as hints for the reader, and an
easy way to adjust how the new localToDevice is constructed.

With this change, we don't need SkSimpleMatrixProvider. SkMatrixProvider
is concrete, so we can use it directly. SkOverrideDeviceMatrixProvider
no longer needs the original provider for anything, so remove that
parameter. It now exists solely to inhibit the hitsPixelCenters flag.

Fix a few spots (SkParticleBinding, some sites in SkRuntimeEffect) where
we used SkSimpleMatrixProvider, even though the local coordinates being
passed did not obey the hits-pixel-centers constraints.

Most importantly, document how localToDeviceHitsPixelCenters works.

b7f5278009 Geometry Processor can output local coord in fragment stage.
Currently GPs inform the program builder of the variable that contains
the local coordinates and it is assumed to be defined in the VS.
Additionally, the builder process will attempt to lift derived
coordinate computations to the VS as varying outputs when they are a
linear/projective transformation of the the GP's local coords.

This change makes it so that the GP can state that the local coord
variable is instead available in the fragment stage. If the GP uses
this option then lifting of coordinate transformations to the VS is
blocked.

44f8636b30 Disable SkVMBlitter cache for Programs with trace hooks.
The trace hooks don't participate in the cache key, so the "matching"
Program in the cache may not have the same trace hook pointers as the
Builders. In fact, the trace hook pointers in the cached Program are
very likely to point to objects that no longer exist at all.

We could incorporate the trace hooks into the key, but this seems like a
losing battle--they're raw pointers and are extraordinarily unlikely to
stay consistent over time. Since trace hooks are only used in a
debugging context, where performance is not very important, the simplest
solution is to just exclude programs with trace hooks from the cache
entirely.

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.

668995122f Fix when a glyph has a path
Always call generateMetrics before generatePath so that generateMetrics
can determine which glyph representation to use and if that glyph
representation can be modeled as a path.

Pass an allocator into generateMetrics so that it can set the path to
not existing. This allows generatePath to continue to work as it used
to, creating a path if any path is available. However, generateMetrics
may first set the path to not existing.

Update getPath and internalGetPath to use the path on the glyph if it
has already been set. Update makeGlyph and internalMakeGlyph to always
call generateMetrics first (which is now more like initGlyph).

Update the SkGlyph::PathData to indicate that it is a dev-path and not a
user-path. A user-path will have effects applied to it. A dev-path is
always a resolved path which is always filled -- unless it is hairline.

Update everything else for the knock on effects and to take advantage of
this information.

that we will need references to debug traces inside a public header.
Rather than reference SkVMDebugInfo directly, we now have a simpler

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

d4713ad528 Move trace hooks into the skvm::Builder.
I ran into a snag while trying to hook up SkRuntimeEffect with debug
tracing. Runtime effects only have access to a skvm::Builder, and are
never exposed to the full skvm::Program. SkVMBlitter is responsible for
assembling the full skvm::Program, but is oblivious to runtime effects
and nested skvm sub-programs. Additionally, multiple runtime effects can
(and often do) coexist within a paint.

This CL changes how debug traces are enabled. skvm::Program no longer
has a `attachDebugTrace` method. Instead, this method lives on the
skvm::Builder. Calling `attachDebugTrace` generates a "trace-hook ID"
(which is actually an index into a vector of TraceHook pointers).
Every trace opcode now includes this trace hook ID. When the Builder
assembles a final Program, it copies the TraceHooks into the Program.
The skvm interpreter uses the trace hook ID on the op to dispatch a
trace command to its associated TraceHook.

From a user perspective, this doesn't change very much, but it does
mean that the SkVM Code Generator now supplies a TraceHook for us
(since it adds trace ops to the Builder and needs to know the proper
trace-hook ID).

2756b0ee02 Reduce the number of extra bit_and ops caused by SkVM traces.
Previously, the trace opcodes took a single mask argument, which was
computed as `execution mask & trace mask`. This led to extra bit_ands in
the output, as this value would be need to be recalculated every time
the execution mask changed.

To reduce this cost on program size, the trace ops now take two mask
arguments and require that both must be true. We have four register
slots at our disposal in an Op, which is more than we need, so this
doesn't really cost us anything.

(As an extra minor optimization, if one of the masks is "always-on", we
optimize it away. This avoids burning a register just to hold a ~0
immediate value.)

6e523fdd6e Remove background reset of command pools in Vulkan.
In practice it has been seen that the cost of spinning up and thread and
sending over this small bit of work is not worth the savings of moving
the command pool reset to another thread. Thus we don't currently have
clients taking advantage of this feature. For now I am removing this
feature and we can add it back in later if we find a better use case or
have more total work to send to a helper thread.

Also in this change I reverse the order of resetting the VkCommandPool
and freeing the resources attached to the pool to workaround a driver
bug.

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.

813d84f69a Handle non-finite sigmas in blur image filter
Previously the sigma clamping code would let nans through. I considered
having SkImageFilters::Blur() return nullptr if a nan sigma was given,
but this solution protects from both initial nans and nans/infinities
produced by mapping the CTM. The result is still an un-blurred image so
behaviorally it's no different.

This also cleans up some of the sigma clamping logic redundancy and
comments in the CPU blur code.

25c0e1a8dd GrSlug prototype
A GrSlug encapsulates an SkTextBlob at a certain origin, using a
given paint. Once a blob is converted to a slug, it can be drawn
through a canvas and will obey the canvas's mapping and clipping.

The glyphs encoded as mask will be transformed using bi-linear
interpolation. The other glyphs type will draw as they normally
would. This allows drawing an SkTextBlob using the original
glyph data from the cache.

This also removes the requirement of assigning a trace coordinate; if

Skia relies on the existence of FT_COLR_COMPOSITE_PLUS, FT_ClipBox, and
FT_Get_Color_Glyph_ClipBox for COLRv1 support. However, these were not
available in the released FreeType 2.11.0 headers since the
specification later changed to require these. In addition, since 2.11.0,
FT_PaintRadialGradient changed the types of two of its members and the
Skia code must depend on this change.

Unrelated, the FT_STATIC_CAST macro was added after these changes. So
undefine TT_SUPPORT_COLRV1 if FreeType is less than 2.11.1 unless
FT_STATIC_CAST is defined.

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).

985403a274 Update SkSL benchmarks to use currently generated shaders
Things have evolved since these were last updated. In particular, we no
longer emit binding and set decorations for each individual uniform.
Backends that rely on that (SPIRV, Metal), generate SkSL that has all
the uniforms grouped in a buffer. GLSL emits the uniforms with no layout
qualifiers. SPIRV supported this already (and automatically applied the
default binding/set to the implicitly created uniform buffer). Metal
*almost* supported this - it handled the uniform buffer correctly, but
didn't apply the default binding to any un-decorated samplers.

63dee7ef06 Add minimal GL support for protected backend textures
Bug: b/205516620

Internally, Skia does not have full GL support for protected backend
textures. But there are some clients who know that they need to create
one so that they can render a protected buffer into it. Plumb in support
for clients calling GrDirectContext::createBackendTexture.

GrGLDefines.h:
- Add macros for querying whether a context is protected

GrGLCaps:
- Check whether the GL_EXT_protected_textures extension is present and
the context supports protected.

GrGLGpu:
- Remove failure cases for GrProtected::kYes. Instead, pass the value
down to createTexture where we then set the parameter in GL.

217347528b Improve redundant trace_var elimination.
Previously, we would avoid emitting redundant trace_vars by checking to
see if the slot is being assigned to the exact same Var.ID. However,
this had the potential to eliminate useful trace_vars:

- At the start of execution, slots all contain 0. Code which explicitly
  assigned a zero into a slot would not be shown in a trace. (So things
  like `color = half4(0,1,0,1)` would only emit traces for color.ga.)
- A function call's parameter slots are reused every time it is called,
  so calling a function twice would only emit traces for the parameters
  that aren't the same Val.ID as the previous call.
- A VarDeclaration inside a loop reuses its slot each time through the
  loop, even though conceptually it's a "new" variable.

We now track a slot's "written-to" status. At the start of execution,
no slots have been "written-to". These slots will always emit a
trace_var opcode (fixing the first issue). Also, issuing a function
call or declaring a variable will reset the "written-to" status of the
associated slots (fixing the second and third issues).

When the debugger is not in use, the written-to field is unused.

c809e5ba9f Optimize commutative operations in SkVM.
We now canonicalize commutative operations by ordering their value IDs.
The lower-numbered value ID is always placed first into a commutative
instruction. In other words, this instruction:
   bit_and result, v7, v5

Would be silently converted to this:
   bit_and result, v5, v7

This will allow these two logically-equivalent instructions to be
deduplicated:
   bit_and result, v7, v5
   bit_and result, v5, v7

Of course, deduplicating these ops can unlock additional free CSE/DCE.
The affected instructions are listed in http://review.skia.org/473238

f3726c61d2 [infra] Use Bazel transitions to allow cc_binary to set their own flags
This will hopefully let us pre-package certain binaries (e.g. DM,
fuzz) with more sensible defaults and not make the developer
type out all the settings.

For CanvasKit, which specifies its own build flags, I think I'll
need to make another transition setup, which would go in something
like modules/canvaskit/ck_binary_with_flags.bzl or something.

Some sausage-case-names were converted to snake_case_names as per
go/build-style#target-naming

The example this is based off is worth a look through before
diving into this:

c7a849319f Make path pre-chopping more robust
Exceptionally large control points might require us to chop the path
very deeply. This CL converts the recursive chopping to loop with a
stack of control points on the heap, in order to avoid the risk of
stack overflow. It also adds a bail condition to avoid getting stuck
in endless recursion due to fp32 precision issues.

32071c3f14 Don't draw massively wide strokes with the tessellator
Since we outset the viewport by stroke width for pre-chopping,
astronomically wide strokes can result in an astronomical viewport
size, and therefore an exponential explosion chops and memory usage.
It is also simply inefficient to tessellate these strokes due to the
number of radial edges required. We're better off just converting them
to a path after a certain point

If the device coordinates are constant across every lane, debug traces
can't generate reasonable results. If nothing actually uses the device
coordinates, the extra opcodes should DCE away.

2fb8dac598 Add trace coordinates to SkVMDebugInfo.
The SkVMDebugInfo now includes an skvm::Coord that the caller is
responsible for filling in before converting the program. If it is set,
the value indicates the device coordinates that should be traced. If it
is unset, debug traces will not be emitted at all.

Within the SkVMCodeGenerator, we now have a new traceMask() call which
combines the current execution mask with the trace mask. Tracing opcodes
now pass the result of traceMask() instead of mask(). This will limit
trace data to the selected pixel, instead of tracing the entire draw.

Hopefully, we can remove this special behavior entirely, but as long
as we have this code, let's be somewhat principled.

30970525fd At SkDevice level and below use SkBlender instead of SkBlendMode
Draws that take a primitive with colors (vertices, patch, atlas) allow
the user to specify how the primitive color is blended with SkShader.

At the public level the blend is specified as SkBlendMode. This change
moves the implementation at SkDevice level over to SkBlender.

Future changes to the existing APIs or future APIs could allow clients
to specify SkBlenders instead of SkBlendMode. THis would would allow for
programmable blending between shader and primitive color.

SkShader_Blend now recognizes if it was constructed with a Mode blender
and extracts the mode enum.

SkBlender_Base::asFragmentProcessor no longer assumes that the dstFP's
input color should be args.fDestColor. Instead the caller
must configure that if desired. (We don't want this for drawAtlas, etc).

The `eval` methods take a shader/blender/colorFilter, and we assumed
when assembling the ChildCall expression that the child expression would
be a VariableReference because opaque objects don't participate in
normal expressions. However, comma-expressions were allowed to contain
opaque types. GLSL doesn't allow opaque types in comma-expressions:
