The bug here is very subtle, as is the mitigation.
Quick background on WASM memory, there is an object
called wasmMemory (which might be hoisted into scope for
CanvasKit's pre-js functions), of type WebAssembly.Memory
which is a resizable ArrayBuffer. Emscripten provides the
JS code to initialize this and handle size increases.
Emscripten also provides TypedArray "views" into this buffer.
These are called CanvasKit.HEAPU8, CanvasKit.HEAPF32, etc.
When there is a call to CanvasKit._malloc, wasmMemory may
be resized. If that happens, the previous TypedArray views
become invalid. However, in the same call to _malloc,
emscripten will refresh the views [1]. So, dealing with
CanvasKit.HEAPU8 directly (quick aside, we never expect clients
to mess with these views, only us in our glue JS code
[e.g. interface.js]), should always be safe because if they
were to be invalidated in a call to _malloc, the views would
be refreshed before _malloc continues.
The problem that existed before was when we were passing
CanvasKit.HEAP* as a parameter to a function, in which the
function would call _malloc before using the typed array
parameter:
//... let us suppose wasmMemory is backed by ArrayBuffer D
copy1dArray(arr, HEAPU32);
// The HEAPU32 TypedArray (backed by ArrayBuffer D) is stored
// to a function parameter "dest"
function copy1dArray(arr, dest, ptr) {
// ...
if (!ptr) {
ptr = CanvasKit._malloc(arr.length * dest.BYTES_PER_ELEMENT);
// Suppose _malloc needs to resize wasmMemory and is
// now backed by ArrayBuffer E.
// Note: The field CanvasKit.HEAPU32 is correctly backed
// by ArrayBuffer E, but variable dest still points to a
// TypedArray backed by ArrayBuffer D.
}
// dest.set will fail with a "neutered ArrayBuffer" error
// because ArrayBuffer D is effectively gone (replaced by E).
dest.set(arr, ptr / dest.BYTES_PER_ELEMENT);
The fix here is to pass in the field name indicating the TypedArray
view we want to write our data into instead of using the
view itself as the parameter.

At startup, we allocate a few scratch arrays and then use those
instead of having to malloc and free a bunch of arrays during
runtime.
The benchmark that was added is a bit noisy (probably because
of the garbage collection going on from the created Float32Arrays),
but a few percent faster.
We also don't set the paragraph background/foreground colors to
transparent because we check them being falsey before sending them
over the wire. I noticed that if foreground was transparent black,
no text shows up at all, which was unexpected.

Consider rendering an SkPicture to a 1080p, 4x msaa render target:
1920 * 1080 * (4 color bytes + 1 stencil byte) * 4 samples = 40Mb!
But SkCanvas::drawPicture calls saveLayer, which allocates a duplicate
render target:
40Mb * 2 = 80Mb!!
So with the original 96MB, a quite conservative msaa render target
almost blows out the entire resource cache just on the backing. This
CL bumps up the default cache size to 256MB.

testing, forwarding from Ubuntu to Mac required passing

We were accidentally turning on MSAA via the "antialias" context attrib,
then feeding the render target into Ganesh and saying it was non-MSAA.
This will cause rendering artifacts in Ganesh if MSAA is unknowingly
enabled when we try to do coverage-based AA.
Also, the WebGL spec does not give us control over the exact sample
count or even guarantee that "antialias" means MSAA, so I think it's
best to leave that flag disabled by default. If a client wants MSAA,
they can create their own offscreen surface and blit it into the main
canvas.

Changes are largely mechanical. Non-mechanical changes to support newer
versions of emscripten are enumerated below, in format ${EMSCRIPTEN_VERSION}:
${RELEVANT_CHANGE}.
- 1.39.9: TOTAL_MEMORY has been renamed INITIAL_MEMORY.
- 1.39.12: passing of linker flags to wasm-ld has changed in a way that requires
supplying `--no-entry` to avoid error message "wasm-ld: error: entry symbol
not defined (pass --no-entry to suppress): main".
- 1.39.16: The factory function created by using `MODULARIZE` build option now
returns a Promise instead of the module instance. As such, the ready.js
workaround is removed. Note this is a breaking API change for CanvasKit,
which now uses just `then()` and not `ready().then()`.
- 1.38.33: `emsdk install` hasn't required the `-64bit` suffix on version names
since `1.38.33`, so we remove them. E.g. `emsdk install sdk-1.39.6-64bit`
simply becomes `emsdk install sdk-1.39.16`.

Parse embedded fonts into SkCustomTypefaces, and pass down the text
animation pipeline. Things seem to mostly work for Latin examples.
Most existing Lottie files come with embedded fonts (the option is
enabled by default), so to minimize disruption only use the new
feature as a fallback for typefaces which cannot be resolved otherwise.
Also introduce a builder flag to prioritize embedded fonts over native
(kPreferEmbeddedFonts), and plumb in existing tools for testing.

Add support for external precomp Skottie layers. This allows embedders
to seamlessly mix custom/Lottie content.
General flow:
* embedders register a PrecompInterceptor callback with
the animation builder
* at build time, Skottie invokes the callback for each pre-composed
layer
- the returned ExternalLayer implementation is used instead of the
Lottie layer payload
- (a nullptr value signals Skottie to use the usual Lottie payload)
* at render time, ExternalLayer::render() is called to defer content
rendering to the embedder
Also implement a sample PrecompInterceptor which attempts to substitute
precmp layers matching a given pattern with external Lottie animations:
precomp_name: "__foo.json" -> Animation("foo.json")
This new mechanism is a generalization of (and supersedes) the old
NestedAnimation hack - so we can remove that.

Inside SkOpEdgeBuilder::walk(), when current segment is cubic curve, its shape may be reduced, therefore, the curve points should be determined by the reduction result ‘split->fVerb’ instead of ‘verb’.
Actually, inside this switch case, ‘verb’ is always ‘SkPath::kCubic_Verb’, which makes the ‘fCanAdd’ always true. The outcome of this bug makes the subsequent logic which depends on ‘fCanAdd’ (L301-332) incorrect, and in some cases, fails the whole boolean operation at L329.
The Fiddle below demonstrates how this bug fails a union operation of two paths, by returning an empty path.
