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).

The existing |SkSurface.requestAnimationFrame| API provides a convenient way of
drawing Skia animations using the same idiom as the well known
|Window.requestAnimationFrame|. It gracefully handles providing the caller with
access to the right canvas, as well as flushing after the user-supplied
callback.
The new |SkSurface.drawOnce| API added in this change provides the same
conveniences around access to the right canvas and flushing, but for the
use-case where the user wishes to draw a single frame only. Importantly, this
new API disposes of the SkSurface upon completion, i.e. frees the memory
associated with the underlying pixel storage an surface. This avoids memory
leaks that occur when |SkSurface.requestAnimationFrame| is used for single-frame
purposes.

In the newly introduced LegacyAnimatorAdapter, failure to parse may
leave the value default-constructed. This is problematic for scalar
values (floats).
Catch this condition and initialize explicitly.

Unlike many users of HarfBuzz, the Skia shaper sets HB_BUFFER_FLAG_BOT
and HB_BUFFER_FLAG_EOT flags to inform HarfBuzz that the full context
contains the beginning and end of the paragraph so that it can treat the
beginning and end of the context specially. In reality, the EOT flag
currently does nothing and the BOT flag only has the effect of adding a
dotted circle (if the font provides it) if the first codepoint in the text
and context is a unicode mark. This behavior is generally unwanted, so
just remove it with a note to revisit this decision should HarfBuzz ever
change the effect of these flags.

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

Flutter on the web wants to be able to extract arbitrary frames from
an animated image and pass those into functions like:
drawAtlas, drawImage, drawImageRect
This should allow that to happen w/o having to add lots of variants like
drawAnimatedImage. If this sticks, is drawAnimatedImage still useful?
(maybe it saves a copy?)

We were previously building FreeType2 with the psnames module,
which included large tables of glyphnames [1]. These were only
used in code related to PDF (and only when outputting Type 1
fonts, which is very rare).
Even though the PDF backend isn't in CanvasKit, the compiler
couldn't throw away these massive tables (about 80k in all)
of strings. Since these tables were only used for T1 fonts,
it made sense to tell FreeType not to include the rest of the
T1 related code, which saved about 55k more.
If, one day, we add in support for the PDF backend to CanvasKit,
SK_PDF_DO_NOT_SUPPORT_TYPE_1_FONTS is likely something we'll
want to define.
The roll-freetype.sh is inspired by a script of the same name
in the Chromium repo and aids in the updating of freetype
and our forked config files.

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

With recent deferred image loading changes, Skottie relies on clients
to always/explicitly seek() before drawing a frame.
Some of the existing tools are still attempt to draw before the first
seek() fires (the animation callback is not guaranteed to occur before
the first draw). For these, add an explicit seek(0) after loading the
animation, to ensure valid state.

In certain cases, deferred behavior is desirable (and the extra animator
