79b7134b5f [canvaskit] Add relative SkPath operators
Like with the non-relative forms, we want to be able to
chain these together, but not leak the SkPaths (which happens
if the C++ side returns this). Thus, we have to add in
the JS glue to return the "JS this".

77d9b5c58e [canvaskit] Add tentative support for savelayerrec
It was easier to just add a few saveLayer overrides rather
than try to expose the struct of pointers. SkRect*
was hard/impossible because we have it as a value_object,
which does not support pointers in enscriptem.

15b40236bd [canvaskit] Add various ImageFilters
We are pretty comfy exposing this set for the long-term.

CanvasKit will generally support chains of image filters,
not necessarily arbitrary DAGs, just to simplify the
points needed to expose.

Change the naming around MaskFilters also, I like having
the factories be a class function, just to keep things
a bit better organized and minimize the amount of things
we want to keep on the top level CanvasKit object.

c6fbedc507 [skottie] 3D layer parenting refinements
Observed AE layer parenting semantics:

  * layers are flagged as either 2D or 3D
  * camera applies to 3D layers, but not to 2D layers
  * parented 3D layers treat their ancestor transform chain as 3D (SkMatrix44)
  * parented 2D layers treat their ancestor transform chain as 2D (SkMatrix, ignoring 3D components)

This means that for a given layer, we may need to build two distinct transform chains - depending
on the type of descendant layer being considered.

Furthermore, transforms are animatable and their animators are scoped to a layer controller.  Since
we're potentially building two version of the transform node, we need to ensure all animators for
both of them are transferred to controller object (we still want to only instantiate a single layer
controller and render tree to avoid duplication).  IOW, all dependent layer transforms need to be
considered before "sealing off" a given layer controller.

In order to avoid a layer dependency/topological sort, we can split off the transform tree
construction into a separate pass.  High-level changes:

  -- replace existing LayerAttachContext with CompositionBuilder
     (holds LayerBuilders and other Composition-wide state)

  -- replace LayerRec with LayerBuilder
     (holds Layer-wide state and also caches transform nodes)

  -- pass 1: for each LayerBuilder, transitively build and cache a transform chain
     of a type (2d/3d) determined by the leaf (entry point) layer

  -- pass 2: for each LayerBuilder, build the actual layer content render tree
     and instantiate the layer controller objects

d9e8586d23 [skottie] Fix camera/3D layer transform interactions
Currently, the camera view transform is attached to the render tree as a
TransformEffect.  This means it gets "flattened" to an SkMatrix in isolation,
and does not compose with other layer transforms in 4x4 format.

Refactor the implementation to

  - build the camera transform upfront
  - compose (chain) all layer transforms from this camera transform

This ensures that transform composition happens in SkMatrix44.

E.g. render tree topology change (TE == TransformEffect)

Before:

                        |

      |                                    |
      |                                    |

      |                                    |
  [Layer1]                              [Layer2]
      |                                    |



After:
                      [root]
                        |
                        |

b484e7ce24 hand off frames to encoder as they come
Instead of rendering all .mp4 frames then encoding, we can kick off
rendering and have the encoder consume frames in order as they become
available.

This uses std::promise / std::future pairs to make the handoff: frame
producers fulfill thieir promise by moving their image into set_value(),
and the encoder (main thread) consumes them by moving those images out
of the paired std::future().  It may not be obvious, but the line

    sk_sp<SkImage> img = frame.get_future().get();

does move the image into `img`... gMP4Frames does not hold a ref once
.get_future().get() has returned.  (Though depending on when you look,
the surface still might.)

This lets us get going on encoding as soon as the first frame is ready,
and hypothetically means encoding should finish shortly after the last
frame draws.  But, different frames cost different time to draw, and we
can't control the order they'll return.  We _do_ have control over the
order they're started, and we're doing that exactly wrong using a LIFO
thread pool.  I've added .mp4 encoding starvation stats to show this...
when I run in LIFO order it looks typically something like

    starved min 0ms, med 0ms, avg 4.12333ms, max 2115ms, sum 2474ms
    frame time min 12ms, med 292ms, avg 307.208ms, max 711ms, sum 184325ms
    106.68user 57.27system 0:04.55elapsed 3601%CPU (0avgtext+0avgdata 3159748maxresident)k
    0inputs+1528outputs (0major+772790minor)pagefaults 0swaps

Mirroring the batch order with (i = frame_count - 1 - i) results in less
starvation, less memory usage, better scaling, and a quicker wall time.

    starved min 0ms, med 0ms, avg 0.896667ms, max 382ms, sum 538ms
    frame time min 13ms, med 374ms, avg 344.365ms, max 918ms, sum 206619ms

7edfb69406 Remove SkCurve and SkColorCurve
This was only being used in one effect (and for no good reason). SkSL is
plenty powerful to re-implement something similar if required, at no
real performance cost.

Re-implemented the one effect that used it with simpler math in the
script, updated the copy of that effect in the gallery.

f976e97a97 [skottie] Horizontal-constraint for Shaper *ToFit alignment modes
Currently we only constrain vertically, assuming shaped lines don't
overflow horizontally.  This is not true for very long words.

Update kVisualResizeToFit and kVisualDownscaleToFit to constrain in
both dimensions.

Also drop the early exit condition because

a) it makes less sense when checking in 2 dimensions (there are
multiple answers which fit snugly in one dimension, but we're
ultimately selecting for the largest font size)

b) it probably doesn't trigger much in practice

Existing tests cover the change in behavior.

1ca50524c4 Allow better font fallback.
The intent is to allow the creation of a MakeFontMgrRunIterator which
uses the passed font's typeface as the primary typeface, but uses a
given family name and style as for the request for fallback fonts. This
allows the user to provide the actual request for the primary typeface
as opposed to making a request based on the resolved primary typeface
(which may not be the right thing to do).

To support this, the selection of language for fallback is also added.
Since this information is already in the language iterator, this change
makes the font iterator the lowest priority iterator for consume,
allowing the font iterator to rely on the current value of the language
iterator to provide the language.

In order to allow these changes to be exercised, this also adds a few
generic 'Make' methods for bidi and script. These new methods will use
the best available implementation. These are needed since the most
capable implementations may not always be available (such as on our
testing ios builds).

e3e4b0cfc1 [skottie] Fix motion blur glitches around domain edges
For motion blur we're sampling within some window around a given t.

If t is close to the layer in/out point, things get murky: for samples
which fall outside the layer lifespan, we skip drawing => fewer samples
are accumulated => the opacity of the result drops => visual glitches.

The solution is to modulate the frame alpha based on the number of
*visible* samples, and skip rendering when no samples are visible.

9b8b4558d2 Change ByteCode and ByteCodeFunction to classes
The lack of encapsulation was finally starting to bother me. Had to
change the Interpreter namespace to a struct so that it could be
friended, but otherwise this was a nice and simple cleanup.

Also updated the comments on the two run functions, and renamed
fInputSlots to fUniformSlots, to reflect recent clarification
around in vs. uniform.

b23d66e10a Interpreter: Lots of minor cleanup/refactoring
- Update the parameter lists to both run and runStriped so
  that they're in the same (sane) order, named consistently,
  and always take counts with pointer arguments.
- Add the same count-based safety checks to run that were
  already in runStriped.
- Remove the N parameter to run, it was only used to run
  things one-at-a-time (other than one spot in unit tests),
  and it simplifies the code quite a bit. If you want to run
  multiple times, use the striped version. I also moved that
  functions 'N' earlier in the parameter list, to make the
  pattern of the remaining parameters clearer.
- Remove an interpreter benchmark class that was never used.
