The previous behavior leaked Skia-internal concepts into public SkSL.
Users coming from GLSL will expect that bindable/sampleable objects are
uniform (just like texture2D). This keeps the old support around (and
tested), but updates all of our examples to use 'uniform'.

Auto-resizing and vertical alignment require a non-empty text box. But
currently, the presence of the text box is used to discriminate between
point text [1] and paragraph text [2].
In order to support auto-scaling and v-alignment for point text, we must
decouple the text mode encoding from the text box:
* introduce and explicit LinebreakPolicy property for skottie::Shaper,
and use it to control line breaking instead of the text box presence
* by default, the line breaking policy is initialized per existing
AE/BM semantics: non-empty text box -> paragraph mode,
empty box -> point mode
* the policy can be overridden via the PropertyObserver APIs to enable
point mode auto-resizing and vertical alignment

when fuzzing over there for some fuzzers.
This has all be consolidated and controlled via the defines

As such, we can remove one of the patches that is in oss-fuzz,

There is no more 'inout half4 color'. Effects return their output color.
If an effect wants the input color, it must use the (already existing)
approach of sampling a nullptr input shader.
The change is guarded for Chromium (so we can update their runtime color
filters in skia_renderer.cc).
For the GPU backend, FPs can now override usesExplicitReturn to indicate
that their emitCode will generate a return statement. If that's true,
then writeProcessorFunction doesn't inject the automatic return of the
output color, and emitFragProc will *always* wrap that FP in a helper
function, even as a top-level FP. GrSkSLFP opts in to this behavior, so
that the user-supplied return becomes the actual return in the FP's
emitCode.
Adapting the skvm code to this wasn't too bad: It looks fragile (what
happens if there are multiple returns?), but that's not really possible
today, without varying control flow.

Currently we use a hard-coded name prefix ('$') and the properties are
"namespaced" (the tree hierarchy is part of the key name).
This doesn't work well for most clients looking to test property
manipulation, as they would rather handle similarly named props in
bulk.
E.g. instead of
precomp1.layer1.Group1.COLOR_01
precomp1.layer1.Group1.COLOR_02
precomp1.layer2.Group1.COLOR_01
precomp1.layer2.Group2.COLOR_02
the UI should simply present
COLOR_01
COLOR_02
To support this, introduce a new operation mode for
CustomPropertyManager (kCollapseProperties), and keep the old behavior
around as kNamespacedProperties.
Also drop filtering for markers as anyone interested in markers would
want to see all of them.
Plumb these options all the way into CK (to be added to the player
later).

Find suspicious usage of runtime string comparison functions.
This check is valid in C and C++.
Checks for calls with implicit comparator and proposed to
explicitly add it:
if (strcmp(...)) // Implicitly compare to zero
if (!strcmp(...)) // Won't warn
if (strcmp(...) != 0) // Won't warn
Checks that compare function results (i,e, strcmp) are compared to valid
constant. The resulting value is
< 0 when lower than,
> 0 when greater than,
== 0 when equals.
A common mistake is to compare the result to 1 or -1:
if (strcmp(...) == -1) // Incorrect usage of the returned value.
Additionally, the check warns if the results value is implicitly cast
to a suspicious non-integer type. It’s happening when the returned
value is used in a wrong context:
if (strcmp(...) < 0.) // Incorrect usage of the returned value.

First thought: keep it really simple and just emit seek() events.
Positive |t|s for track playback, negative for track off.
The embedder needs to implement state menagement (playing/not-playing)

2) Some modes (notably intersect) require touching pixels outside the

Introduce an explicit layer node in SkSG, and inject for masks which
require it.
Also refactor Subtract to use more natural blend and pathops modes,

Two issues:
1) For static keyframes (start_value == end_value) AE yields horizontal
orientation (0 tangent). We technically have the same logic in
Skottie, but our value deduplication logic interferes: the two
consecutive equal values are consolidated, and the result ends up
holding the spatial lerp info for the next frame => our hold frames
auto-orient for the beginning of the next keyframe.
Fix: skip value deduplication when spatial lerp is present.
2) The very last keyframe is always static and holds no spatial info.
AE retains the orientation of the previous frame, but Skottie yields
0 tangent.
Fix: the easiest way to accomplish AE semantics is to detect when
we're dealing with the last keyframe, and swap with the previous
keyframe with an adjust weight of 1 (to select the end value). This
produces the same lerp result (because keyframed values are always
contiguous) and also respects the orientation of the prev frame.
