This fuzz creates a blur that has w = 1 and h = 2^31 - epsilon.
And a filter sigma of 360. This causes the intermediate
buffer size > 2^31. This causes the multiply in the following
code SkMaskBlurFilter.cpp:1023:
tmpStart + tmpW * tmpH
to overflow. Because tmpW = source height, which is near 2^31,
and tmpH is about 3*360.
Cause the blur to fail if the intermediate buffer is > INT_MAX.

Previously, `generate_default_before_children_glue_code` would create
a new variable but wouldn't actually return its name. This made it
difficult to use in several ways:
- The caller would need to manually regenerate the variable name
- We may just want the matrix expression, not a whole new variable
(in the context of a runtime effect, we might not have the luxury of
freely inserting new statements into the code)
We now have a function `pre_local_matrix_for_entry` which returns the
pre-local matrix expression but does not assign it to a variable at
all. This simplifies our implementation of `emit_glue_code_for_entry`
because we no longer need to recreate the variable name.

Previously, `emitGlueCodeForEntry` assumed that every child should be
invoked exactly once, and those values should be passed into the shader
snippet.
This model does not work for Runtime Effects. A runtime effect is
free to invoke its children multiple times, or not at all. Now,
glue code generators can choose to call `emit_child_glue_code` and get
the old behavior, or they can handle children their own way as
needed. In practice, GenerateDefaultGlueCode uses this function, but
no other glue-code generators currently use children or have a need
to call it.
This CL also changes `emitGlueCodeForEntry` into a free function
instead of a private method. This makes it possible for us to use
this function from the glue-code generators, which are not part of
SkShaderInfo. SkShaderInfo is documented as a "simple collection
object," so this is probably the right design anyway.

Notes to reviewer:
- modules/canvaskit/npm_build/types/canvaskit-wasm-tests.ts
is not actual test code that is executed. It is parsed with
our types (index.d.ts) only, as a way to make sure the
declared types match up with how one would write code.
- MakeDisplacementMap looked a bit strange when I tried to
use it. It might be easiest to debug if we land as is,
so we can use jsfiddle to test dynamic parameters.
- modules/canvaskit/package-lock.json was updated by running
npm audit fix.
- There are two copies of the test cases, one for the old
way, and one for Bazel. Getting Bazel on the CI is currently
blocked (http://review.skia.org/547576)
- I am adding all the image filters in by default for now,
we can measure code size and adjust them if needed later.

PredefinedColorSpace was not available before then.
To upgrade the package-lock.json, I deleted the node_modules
folder in npm_build and the existing package-lock.json,
then ran `npm install` (using npm 7.20.6, along with node
14.15.0).
There was still an issue with the order of types in
the type union for readPixels. Apparently, TS changed
this slightly in a version upgrade. To address this,
I added an "or" to that type assertion, along with
a comment.
I double-checked the necessity of reference types="@webgpu/types"
and this is needed to use things like GPUTexture and
GPUDevice.

When allocating memory with malloc(), allocators can provide a larger
size than requested. SkArenaAlloc tries to guess what jemalloc would
return, and align its allocation requests on the to-be-provided
size. Some platforms (e.g. glibc or bionic with malloc_usable_size(),
macOS with malloc_size()) can provide the actual value.
This CL adds support to skia's malloc() wrappers to get this data, and
to SkArenaAlloc to use it. Note that as is, this is a no-op in skia
proper. Indeed, clients can (and do, for instance Chromium does)
override sk_malloc() (and friends), so Skia cannot assume that
sk_malloc() memory comes from malloc().
To implement this, a client needs to override sk_malloc_usable_size() to
return the actual value.

This CL adds two new APIs to SkCanvas: getBaseProps, and getTopProps.
SkCavas::getBaseProps is functionally identical to getProps, but returns
the SkSurfaceProps by value, rather than via an 'out' parameter.
SkCanvas::getProps is now considered deprecated.
SkCanvas::getTopProps returns the 'currently active' SkSurfaceProps,
i.e., it returns the props from the "top device". This is useful
because the SkSurfaceProps can change when creating new layers.

In practice, calls to main are not meaningful:
- If main is called in live code, it's recursive
- If main is called in dead code, it's eliminated
However, if optimization/dead-stripping is turned off, the dead-code
case emits bad code in our GLSL/Metal backends. Rather than add a
special case to the backends to work around an error in a meaningless
edge case, we now reject the function call entirely.
Prototyping main() is, as far as I can tell, harmless, so this
continues to be allowed.
