AE supports dashing all strokes. Dashes are specified as an arbitrary
number of intervals (alternating dash/gap) plus a start offset.
All values can be animated independently (but of course!).
- implement a SkSG dash effect (based on SkDashPathEffect)
- expand the shape builder logic to allow local geometry adjustments
(kind of a bummer that dashing is a stroke/paint property as opposed
to a geometry effect in AE)

By default, per-character AE transforms are anchored on the glyph
baseline, mid-advance.
To support:
- extend SkottieShaper to track per-fragment ascent and advance
- adjust the fragment transform origin for (advance/2,0)
As an optimization, we only track the anchor point in the presence
of origin-dependent animators (scale & rotation ATM).
(note: the ascent info is going to be used in a follow up CL to support
relative anchor point adjustments)

This CL has a complicated back story, but it's concrete change is
simple, just turning the warning on and converting a bunch of
return foo;
to
return std::move(foo);
These changes are exclusively in places where RVO and NRVO do not apply,
so it should not conflict with warnings like -Wpessimizing-move.
Since C++11, when you return a named local and its type doesn't match
the declared return type exactly, there's an implicit std::move()
wrapped around the value (what I'm making explicit here) so the move
constructor gets an opportunity to take precedence over the copy
constructor. You can read about this implicit move here under the
section "automatic move from local variables and parameters":
https://en.cppreference.com/w/cpp/language/return#Notes.
This situation comes up for us with smart pointers: a function declares
its return type as std::unique_ptr<Base> or sk_sp<Base>, and we return a
std::unique_ptr<Impl> or sk_sp<Impl>. Those types don't match exactly,
so RVO and NRVO don't come into play. They've always been going through
move constructors, and that's not changed here, just made explicit.
There was apparently once a bug in the C++11 standard and compilers
implementing that which made these copy instead of move, and then this
sort of code would do a little unnecessary ref/unref dance for sk_sp,
and would entirely fail to compile for uncopyable std::unique_ptr.
These explicit moves ostensibly will make our code more compatible with
those older compilers.
That compatibility alone is, I think, a terrible reason to land this CL.
Like, actively bad. But... to balance that out, I think the explicit
std::move()s here actually help remind us that RVO/NRVO are not in play,
and remind us we're going to call the move constructor. So that C++11
standard bug becomes kind of useful for us, in that Clang added this
warning to catch it, and its fix improves readability.
So really read this all as, "warn about implicit std::move() on return".
In the end I think it's just about readability. I don't really hold any
hope out that we'll become compatible with those older compilers.

Generally, keyframe values live in dedicated storage, and are tracked in
keyframes based on their index.
This separation is not necessary for float values, as their storage size
is the same as their index's:
- update keyframes to store value records (VRecs), which can hold
either external value indices or inline floats
- introduce a scalar animator specialization which operates on float
VRecs and doesn't require dedicated value storage

For each Lottie keyframe, we currently store interpolation
*segments*:
{
t0, v0
t1, v1
cubic_mapper
}
This is quite redundant:
- kf(n).t1 == kf(n+1).t0 for all keyframes
- kf(n).v1 == kf(n+1).v0 for all non-constant keyframes
Refactor to store single keyframe records:
{
t, v
mapping
}
To identify constant keyframes, since we no longer store
explicit hard stops, we now tag each record with a "mapping"
selector:
0 -> constant keyframe
1 -> linear keyframe
> 1 -> cubic keyframe (adjusted cubic mapper index)
This reduces the storage size by 2/5, and yields overall cleaner
logic (as we're no longer back-filling info as we parse).
Also add a handful of unit tests to lock down limit semantics
(keyframe segments are left-inclusive/right-exclusive).

Currently, property animators use lambda captures (std::function<>) to push
values to adapters and then to the scene graph. Some downsides:
* complex lambda captures are expensive in terms of object code size
* adapters with multiple animated properties don't synchronize/quiesce: each individual property tick triggers a SG
synchronization, possibly with inconsistent state (as animator running
order is unspecified)
* there is no enforced scoping, resulting in fragile constructs when SG
fragments are discarded
This CL introduces a simplified and more robust animator pattern:
* property animators are scoped to explicit containers
* instead of capturing arbitrary value functors, animators only capture
a pointer to the target value
Some implementation details:
* keyframe/interpolation logic is pretty much unchanged (just relocated)
* introduced AnimatablePropertyContainer - a base class for animatable
adapters
* legacy binding functions are refactored based on the new mechanism
(they now/transitionally inject adapter objects)
* converted a handful of effects, to exercise trivial refactoring patterns
* converted the text animator goo, to exercise non-trivial refactoring:
- detecting value changes is now trickier (no more lambda magic)
- value adjustments must be hoisted into adapter logic (no more lambda magic)
- all dependent animated values (selectors, etc) must be scoped to the
text adapter to avoid lifetime issues

Currently, we treat track matte source layers (tagged with td:1) as single-shot mask triggers:
we apply once to the following layer, then move on.
But track mattes can cascade: a layer with a matte can itself be applied as a track matte for the
following layer.
Also, for matte/masking purposes, only the layer content is being considered (ignoring blend mode
and any masks applied to the matte itself).
To support this, refactor the layer attachment code:
- instead of tracking the presence of a single-shot matte source, always track
previous layer content trees
- instead of triggering matte attachment in the presence of a matte source, trigger based on
the matte *target* property (tt: X)
- log errors on unknown matte modes

Instead of always grabbing the first frame at load time, only do so for
single-frame images.
For multi-frame images, defer frame resolution until actually needed
(at seek time).
There's a slight complication in dealing with image scaling: since we
no longer know the intrinsic size of the frames upfront, we need to
set up a transform effect preemptively for multi-frame images, and
update on the fly when the frames are resolved. This is not
necessarily bad, because theoretically frames could have different
sizes.
