This involves a refactor of how we deal with paint.
Now, we have a source-of-truth paint that is copied
and modified for each of fill/stroke/shadow.
Adds preliminary support for blend modes.
Most of what remains is text, images, and gradients.

This re-works the subpath model and does transforming
of ports in JS rather than in C++; the latter was not easy
to conform to the Canvas Spec, especially for changing
transforms in the middle of a path.
Additionally adds jpeg to the available images it can produce.

These changes expose the arc function for SkPath. The ApplyAddArc function is a copy from the PathKit bindings.
Also exposed the PNG and JPEG formats from the SkEncodedImageFormat enum and the SkImage::encodeToData overload that accepts format and quality options. The direct binding of encodeToData was replaced with a pre-js wrapper that calls the appropriate private overload
We are working on a PostCSS conic gradient polyfill plugin and want to use the CanvasKit to generate it.
Problem is - it lacks the arc function that technically exists but isn't exposed. And it would be really great to have encodeToData with options since generated PNGs are quite large.

I can probably write most, if not all, of a Canvas API in
JS using the SkCanvas and SkPaint objects. This lets us expose
the fancier API and optionally have a more familiar API.
This is controlled at compile time, i.e. bring in the extra
JS or not.
There is still plenty of the API that needs working, but
this is meant to outlay the plans of where this is going.

PathOps added a cheat some time ago to reduce
fuzzer bugs by scaling down very large paths,
with the hope that it would make the math more
sane.
This had the side-effect of causing small edges
to disappear altogether if the bounds is large
enough.
Removing the scaling causes a single regression to
one fuzz-generated bug. That path succeeeded with
scale by eliminating the troublesome tiny contour.
Eliminating the scale may fix the CCPR-related bug
discovered by Flutter, or at least uncover the next
bug.
I would expect more fuzzer bugs to appear with
this change; paths with large and small values will
no longer have the small values removed.

Breaking Changes (should be minor, as it's mostly just things
for testing):
- PathKit.ApplyPathOp should have returned a new SkPath, but didn't.
It now does and is named "MakeFromOp", which makes the convention of
"Have 'make' in name, needs delete" more consistent.
- PathKit.FromCmds(arr) now only needs to take the JS Array and
will handle the TypedArrays under the hood. If clients want to deal
with TypedArrays themselves, they can use _FromCmds(ptr, len) directly.
- PathKit.MakeLTRBRect is now just PathKit.LTRBRect. The thing
returned is a normal JS Object and doesn't need delete().
As per custom with v0 apps, we are updating the minor version
to v0.3.0 to account for breaking changes.

Consolidates the karma files into one for docker/asmjs/wasm and all
combinations.
The asm.js build seems to have some small imprecisions that we didn't
see as much as with WASM, probably due to JS limitations/differences
to c++'s floats.
To address these, I've marked some (5) tests in PathOps* as flaky
because they fail on Release, Debug or Test versions of the asm.js build.
Other then that, asm.js seems basically identical to the WASM.
WASM is much smaller, 416k vs 877k and seems to load faster (not
measured).

Breaking Changes:
- All method calls that mutate a path now return the same JS path
object to allow chaining (moveTo, lineTo, trim, op, simplify, etc).
Pre-existing code likely will need to have some delete() methods
removed because the path will be deleted multiple times. See
chaining.js for this code (basically, we wrote our own binding code
since the default code wasn't quite flexible enough)
- GetCanvasFillType -> GetFillTypeString (Was in https://skia-review.googlesource.com/c/skia/+/147209)
Since Canvas and SVG use the same strings, it seemed logical to make
them share.
- stroke() now takes a single object instead of 3 params. This object
currently can have up to 4 params, cap, join, width, miter_limit.
This object can be expanded on in future versions as more configuration
options are added.
As per custom with v0 software, we bump the minor version to 0.2.X
to indicate breaking changes in a pre-release software package.
Other changes of note:
- Simple tests added for effects (see effects.specs.js) A follow up
CL will handle the Gold (correctness tests)
- Simple tests added for equals and copy constructors (from https://skia-review.googlesource.com/c/skia/+/147209)
- Added transform() to allow for arbitrary matrix transforms
- Added SimpleMatrix as a value_array, which means users can
provide a 9 element array which will be converted to SimpleMatrix
and then SkMatrix on the C++ side.
- Renamed helpers_externs.js to externs.js and expanded it greatly.
This was necessitated by the code written in chaining.js
- Fixed a few bugs in previous tests (svg gold test race condition,
uncaught exception in svg reporting)
See also https://skia-review.googlesource.com/c/skia/+/147209 which
allows .moveTo .lineTo, etc to chain on the C++ SkPath.
