There was a break that was solved by adding -lGL to our link
steps. I discovered a few extra flags to aid in debugging builds
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.

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.

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.

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`.

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.

- removed -Idirectives from BUILD.gn
- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout
so that #include "include/config/SkUserConfig.h" always
