Its effect is small and we want to rely on SkReadBuffer being available.
Size changes:
- canvaskit uncompressed: 6,864,481 --> 6,864,481 ( no change )
- canvaskit compressed: 2,667,117 --> 2,667,117 ( no change )
- pathkit uncompressed: 329,187 --> 330,679 (+ 1.5K, +0.5%)
- pathkit compressed: 134,158 --> 134,672 (+ 0.5K, +0.4%)
- flutter : 1,302,108 --> 1,322,568 (+20.0K, +1.6%)
The Flutter change is the biggest mystery, as bloaty only pegs
SkReadBuffer as 3.9K. The rest must come from other files including
SkReadBuffer.h not being able to see and inline away SkReadBuffer
routines? Feels like SK_DISABLE_EFFECT_DESERIALIZATION isn't trimming
enough?
PS 4-6 have an idea to push SK_DISABLE_EFFECT_DESERIALIZATION further.

This method is called every time we paint a styled text range to find its cluster range.
Instead of scanning all the clusters in the run we can use
a helper table that for every UTF8 byte keeps its cluster.
(So the most important part of the change is this table in Paragraph)
Should have done it long time ago but fixing bugs seemed to be more
important than performance.

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.
