LottieRenderPooler is designed to manages rendering
instances(paints) efficiently through a simple pooling
mechanism to resuse among the animations
This replaces the previous individusal paints implemenations
among solidfill, precomp vierport and pictures,
also fix a potential paints corruption problems.
The current development of the expression engine is experimental.
It does not support multi-threading.
Therefore, when tvg::Initializer::init() is configured
with more than one thread, expressions will be automatically disabled.

introduced the JerryScript engine to interpret Lottie
expressions, enhancing the capability to support runtime
programmable animation logic within Lottie expressions
spec. This feature, based on js scripting, represents
the most complicated addition to the Lottie spec so far.
ThorVG probably could includes an option to toggle
this feature at build time, allowing for customizable user
configurations according to specific requirements.
removed unused features for the optimal size:
- DEBUGGER
- MEM_STATS
- SNAPSHOT
- BUILTIN_JSON
- BUILTIN_PROXY
- BUILTIN_REFLECT
- BUILTIN_ATOMICS
- PROMISE_CALLBACK
- MODULE_SYSTEM
- SYSTEM_PORT
This is an experimental version.
Please manually enable the 'lottie-expressions' in meson.build
when you wish to use it.

This class extends the Animation and serves advanced Lottie features.
It's designed to separately have Lottie Animation's unique specs.
For now, this will have Slot overriding feature,
you can include <thorvg_lottie.h> for its extensive features.
@APIs:
- Result LottieAnimation::override(const char* slotJson) noexcept;
- static std::unique_ptr<LottieAnimation> LottieAnimation::gen() noexcept;
