This is a massive breaking change for all existing users of CanvasKit.
It will be (one of the only) changes in 0.19.0 to make the transition
easier.
Suggested reviewing order:
- index.d.ts (to see type changes). Notice SkPicture still has Sk
prefix, but no other types do (this felt "right" since Sk is
part of the name of the type, but I can be swayed on this).
- canvaskit-wasm-tests.ts
- tests/*.spec.js
- interface.js and helper.js
- html examples
- markdown files

I don't think we need the extra bin folder; we should be
able to declare our types all in index.d.ts.
This also checks in the package-lock.json, now that we
have devDependencies to run those type checks.
`make typecheck` runs the typecheck tests.
The tsconfig.json and tslint.json were created following
the instructions at https://github.com/microsoft/dtslint
and using the DefinitelyTyped rules.

Adds a new helper that creates a GrBackendRenderTarget using
GrGpu and then wraps it in a SkSurface. Uses the SkSurface
release proc to delete the BERT using GrGpu.
Upgrades GrGpu::createTestingOnlyBackendRenderTarget to create MSAA

Updates many tests/tool to call sites to use the helper instead of
SkSurface::MakeFromBackendTextureAsRenderTarget.
Adds syncToCpu bool to SkSurface:: and GrContext::flushAndSubmit.

Auto-resizing and vertical alignment require a non-empty text box. But
currently, the presence of the text box is used to discriminate between
point text [1] and paragraph text [2].
In order to support auto-scaling and v-alignment for point text, we must
decouple the text mode encoding from the text box:
* introduce and explicit LinebreakPolicy property for skottie::Shaper,
and use it to control line breaking instead of the text box presence
* by default, the line breaking policy is initialized per existing
AE/BM semantics: non-empty text box -> paragraph mode,
empty box -> point mode
* the policy can be overridden via the PropertyObserver APIs to enable
point mode auto-resizing and vertical alignment

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.

There is no more 'inout half4 color'. Effects return their output color.
If an effect wants the input color, it must use the (already existing)
approach of sampling a nullptr input shader.
The change is guarded for Chromium (so we can update their runtime color
filters in skia_renderer.cc).
For the GPU backend, FPs can now override usesExplicitReturn to indicate
that their emitCode will generate a return statement. If that's true,
then writeProcessorFunction doesn't inject the automatic return of the
output color, and emitFragProc will *always* wrap that FP in a helper
function, even as a top-level FP. GrSkSLFP opts in to this behavior, so
that the user-supplied return becomes the actual return in the FP's
emitCode.
Adapting the skvm code to this wasn't too bad: It looks fragile (what
happens if there are multiple returns?), but that's not really possible
today, without varying control flow.

Currently we use a hard-coded name prefix ('$') and the properties are
"namespaced" (the tree hierarchy is part of the key name).
This doesn't work well for most clients looking to test property
manipulation, as they would rather handle similarly named props in
bulk.
E.g. instead of
precomp1.layer1.Group1.COLOR_01
precomp1.layer1.Group1.COLOR_02
precomp1.layer2.Group1.COLOR_01
precomp1.layer2.Group2.COLOR_02
the UI should simply present
COLOR_01
COLOR_02
To support this, introduce a new operation mode for
CustomPropertyManager (kCollapseProperties), and keep the old behavior
around as kNamespacedProperties.
Also drop filtering for markers as anyone interested in markers would
want to see all of them.
Plumb these options all the way into CK (to be added to the player
later).

and I've left those in (they aren't too noisy IMO).
This changes the base dockerfile to use the official emscripten one.
Code size delta for full build is +5 kb
For future reference, emsdk decides which "library JS" files to
pull in using a83ba99d60/tools/building.py (L1553)
Those JS files live in src (e.g. a83ba99d60/src/library_html5_webgl.js (L222))
and define functions that the C++ code can call.
I'd like to follow-up on what -lEGL is doing.
Also, since the new image no longer has depot_tools, we need
to make docker/skia-wasm-release/Dockerfile install it.

Objects in the symbol table are intentionally constant. However, when
converting "ExternalValue" AST nodes into symbols via symbol table
lookup, IRGenerator::convertIdentifier was casting away constness
because ExternalValueReference held a non-const pointer. Fixing this
involved significant ripple-effect additions of "const" throughout the
ExternalValue class and its subclasses.
These changes generally appear to be benign, but one interesting edge
case is `ExternalValue::write`, which intuitively does not seem to make
sense as a const method. However, invoking `write` should not alter the
ExternalValue object itself; rather, it is intended to alter the
*external value* that is being referenced. (In practice, nothing invokes
write() anyway except for one unit test, which continues to pass.)
This issue was discovered while converting casts to `as<T>()` calls.

https://clang.llvm.org/extra/clang-tidy/checks/bugprone-suspicious-string-compare.html
Find suspicious usage of runtime string comparison functions.
This check is valid in C and C++.
Checks for calls with implicit comparator and proposed to
explicitly add it:
if (strcmp(...)) // Implicitly compare to zero
if (!strcmp(...)) // Won't warn
if (strcmp(...) != 0) // Won't warn
Checks that compare function results (i,e, strcmp) are compared to valid
constant. The resulting value is
< 0 when lower than,
> 0 when greater than,
== 0 when equals.
A common mistake is to compare the result to 1 or -1:
if (strcmp(...) == -1) // Incorrect usage of the returned value.
Additionally, the check warns if the results value is implicitly cast
to a suspicious non-integer type. It’s happening when the returned
value is used in a wrong context:
if (strcmp(...) < 0.) // Incorrect usage of the returned value.

Looking at audio layer support for Skottie, we need an API to
externalize audio asset loading and playback.
Similar approach to the other resource types for loading, but in
addition we also delegate playback control to the embedder.
First thought: keep it really simple and just emit seek() events.
Positive |t|s for track playback, negative for track off.
The embedder needs to implement state menagement (playing/not-playing)
and optional synchronization (if animation playback is not real time).

`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.

Previously one could not color text with paints, even though TextStyle's foregroundColor and
backgroundColor fields are SkPaints. Canvaskit only exposed these as colors in order to allow
SimpleTextStyle to be a value object that would not have to be deleted by the user.
CanvasKit.Paint is a bound SkPaint. I wanted to allow a user to pass a paint to be used
in a text style without alterting SimpleTextStyle's status as a value-object.
So I've added a new bound method, pushPaintStyle which acts just like pushStyle but allows
a foreground and background paint to be supplied which are used to override the existing paints.
The user is responsible for deleting these paints.
Sorry for the kludgy design, if you have got a more elegant way, I'm open to suggestions.

Although it appeared that the experimental_simd CanvasKit build was
working, the build was not producing actual wasm SIMD operations. This
CL fixes that issue by changing the build arguments.
This issue also fixes an incorrect type issue with the SkVx wasm SIMD
implementation.

Two issues:
1) For static keyframes (start_value == end_value) AE yields horizontal
orientation (0 tangent). We technically have the same logic in
Skottie, but our value deduplication logic interferes: the two
consecutive equal values are consolidated, and the result ends up
holding the spatial lerp info for the next frame => our hold frames
auto-orient for the beginning of the next keyframe.
Fix: skip value deduplication when spatial lerp is present.
2) The very last keyframe is always static and holds no spatial info.
AE retains the orientation of the previous frame, but Skottie yields
0 tangent.
Fix: the easiest way to accomplish AE semantics is to detect when
we're dealing with the last keyframe, and swap with the previous
keyframe with an adjust weight of 1 (to select the end value). This
produces the same lerp result (because keyframed values are always
contiguous) and also respects the orientation of the prev frame.

AE allows animating the line spacing text property [1].
Observed semantics:
- spacing is applied as an offset to all fragments in a line
- for selector/partial coverage, the spacing for a given line
is the average of the computed spacing for each fragment
- spacing is cumulative (applies to all lines following)
Plumb the new animator prop ("ls") and expand the existing line
tracking logic to also apply computed spacing offsets.
(also requires a Bodymovin update to export the line spacing property)

with SIMD instructions in the compiled WASM. This build of
CanvasKit works in Chrome Canary 86.0.4186.0
with chrome://flags#enable-webassembly-simd enabled.
Also add WebAssembly-specific intrinsics to SkVx.h to enable
support for almost all native SIMD operations in CanvasKit WebAssmebly.
Also add a Skia/modules/canvaskit/wasm_tools/SIMD folder which contains
build_simd_test.sh for testing whether WASM SIMD intrinsics operations
are actually being used by skvx, and for testing correctness of
WASM SIMD operations. Also contains simd_float_test.cpp and
simd_int_test.cpp which serve as documentation for which operations are
correctly turned into WASM SIMD operations by emscripten.

https://skia-review.googlesource.com/c/skia/+/297896 draws
several paths with over 1000 points (one has ~250k) and
was pretty slow. We already had a way to provide a flat(ish)
array of all the verbs, points and weights mushed together
(although that should be cleaned up to prefer taking a 1d
array).
This adds an additional way to provide multiple verbs,
points, (and optionally weights, if conics are used) to CanvasKit.
This makes things dramatically faster because of batch copying
the values between JS and WASM (or using Malloc).
Additionally, the above CL revealed a need to be able to
use a subsection of a Malloc'd array efficiently. Thus,
I added subarray as a method of the Malloc object, which
can be used effectively as a pointer (i.e. no copying).

CanvasKit.MakeImageFromEncoded, when used with Browser APIs for loading/decoding images.
- `CanvasKit.MakeImageFromCanvasImageSource` takes either an HTMLImageElement,
SVGImageElement, HTMLVideoElement, HTMLCanvasElement, ImageBitmap, or OffscreenCanvas and returns
an SkImage. This function is an alternative to `CanvasKit.MakeImageFromEncoded` for creating
SkImages when loading and decoding images. In the future, codesize of CanvasKit may be able to be
reduced by removing image codecs in wasm, if browser APIs for decoding images are used along with
`CanvasKit.MakeImageFromCanvasImageSource` instead of `CanvasKit.MakeImageFromEncoded`.
- Three usage examples of `CanvasKit.MakeImageFromCanvasImageSource` in core.spec.ts. These
examples use browser APIs to decode images including 2d canvas, bitmaprenderer canvas,
HTMLImageElement and Blob.
- Added support for asynchronous callbacks in perfs and tests.
Here are notes on the image decoding approaches we tested and perfed in the process of finding ways
to use Browser APIs to decode images:
1. pipeline:
ArrayBuffer → ImageData → ctx.putImageData →
context.getImageData → Uint8Array → CanvasKit.MakeImage
❌ Problem: ImageData constructor expects decoded bytes already.
2. interface.js - CanvasKit.ExperimentalCanvas2DMakeImageFromEncoded (async function)
pipeline:
ArrayBuffer → Blob -> HTMLImageElement ->
draw on Canvas2d -> context.getImageData → Uint8Array →
CanvasKit.MakeImage
✅ Works
⏱ Performance: 3rd place (in my testing locally)
3. interface.js - CanvasKit.ExperimentalCanvas2DMakeImageFromEncoded2 (async function)
ArrayBuffer → Blob → ImageBitmap → draw on Canvas2d →
context.getImageData → Uint8Array → CanvasKit.MakeImage
✅ Works
⏱ Performance: 2nd place (in my testing locally)
4. interface.js - CanvasKit.ExperimentalCanvas2DMakeImageFromEncoded3 (async function)
ArrayBuffer → Blob → ImageBitmap →
draw on canvas 1 using bitmaprenderer context →
draw canvas 1 on canvas 2 using drawImage → context2d.getImageData →
Uint8Array → CanvasKit.MakeImage
✅ Works
⏱ Performance: 1st place (in my testing locally) - quite surprising, this in some ways seems to be a more roundabout way of CanvasKit.ExperimentalCanvas2DMakeImageFromEncoded2, but it seems bitmaprenderer context is fairly fast.
