Flutter on the web wants to be able to extract arbitrary frames from an animated image and pass those into functions like: drawAtlas, drawImage, drawImageRect This should allow that to happen w/o having to add lots of variants like drawAnimatedImage. If this sticks, is drawAnimatedImage still useful? (maybe it saves a copy?)

Prerequisites
To compile CanvasKit, you will first need to install emscripten. This
will set the environment EMSDK (among others) which is required for
compilation.
Compile and Test Locally
make release
make local-example
This will print a local endpoint for viewing the example. You can experiment
with the CanvasKit API by modifying ./canvaskit/example.html and refreshing
the page. For some more experimental APIs, there's also ./canvaskit/extra.html.
For other available build targets, see Makefile and compile.sh.
For example, building a stripped-down version of CanvasKit with no text support or
any of the "extras", one might run:
./compile.sh no_skottie no_particles no_font
Such a stripped-down version is about half the size of the default release build.
