b77f3ca024 common: introduced designated memory allocators
Support the bindings to be more integrable with a system's coherent memory management.

Pleaes note that thorvg now only allow the desinated memory allocators here:
malloc -> tvg::malloc
calloc -> tvg::calloc
realloc -> tvg::realloc
free -> tvg::free

5c950b783c renderer: handle edge cases for trimming with dashing
- In cases where the begin and end values of trimming did not
result in trimming (end - begin > 1), trimming was ignored.
However, when the stroke is also dashed, this case affects
the shift of the point where the first dash becomes visible.

- Trimming that passes through the curve's start point (like -0.1:0.1)
requires passing through the curve twice. The points obtained from
both passes must be joined - visible when dashing
Cases for simultaneous = true have been handled.

78cfc33f4c lottie: support frame tweening feature
frame tweening allows user to interpolate two frames
over a speicified duration. This Tweening functionality
can be particularly powerful when combined with state-based
(a.k.a. Marker) animation playback in Lottie.

For example, apps support state machine based animations,
where the transition sequences between states are not linear
and can occur in highly irregular directions.

Experimental APIs:
- Result LottieAnimation::tween(float from, float to, float progress)
- Tvg_Result tvg_lottie_animation_tween(Tvg_Animation* animation, float from, float to, float progress)

- uint8_t Paint::unref(bool free = true)
- uint8_t Paint::refCnt() const

ed01ef717e api: revise the spec
Remove the requirement for unique_ptr in the function prototypes.
This change will simplify the API usage, making it more streamlined
and user-friendly. However, memory management will now be the
responsibility of the user.

C++ API Modification:
- Result Paint::mask(std::unique_ptr<Paint> target, MaskMethod method) -> Result Paint::mask(Paint* target, MaskMethod method)
- Result Paint::clip(std::unique_ptr<Paint> clipper) -> Result Paint::clip(Paint* clipper)
- virtual Result Canvas::push(std::unique_ptr<Paint> paint) -> virtual Result Canvas::push(Paint* paint)
- std::unique_ptr<LinearGradient> LinearGradient::gen() -> LinearGradient* LinearGradient::gen()
- std::unique_ptr<RadialGradient> RadialGradient::gen() -> RadialGradient* RadialGradient::gen()
- Result Shape::strokeFill(std::unique_ptr<Fill> f) -> Result Shape::strokeFill(Fill* f)
- Result Shape::fill(std::unique_ptr<Fill> f) -> Result Shape::fill(Fill* f)
- std::unique_ptr<Shape> Shape::gen() -> Shape* Shape::gen()
- std::unique_ptr<Picture> Picture::gen() -> Result Picture::push(Paint* paint)
- std::unique_ptr<Scene> Scene::gen() -> Scene* Scene::gen()
- Result Text::fill(std::unique_ptr<Fill> f) -> Result Text::fill(Fill* f)
- std::unique_ptr<Text> Text::gen() -> Text* Text::gen()
- std::unique_ptr<SwCanvas> SwCanvas::gen() -> SwCanvas* SwCanvas::gen()
- std::unique_ptr<GlCanvas> GlCanvas::gen() -> GlCanvas* GlCanvas::gen()
- std::unique_ptr<Animation> Animation::gen() -> Animation* Animation::gen()
- Result Saver::background(std::unique_ptr<Paint> paint) -> Result Saver::background(Paint* paint)
- Result Saver::save(std::unique_ptr<Paint> paint, const char* filename, uint32_t quality = 100) -> Result Saver::save(Paint* paint, const char* filename, uint32_t quality = 100)
- std::unique_ptr<Saver> Saver::gen() -> Saver* Saver::gen()
- std::unique_ptr<Accessor> Accessor::gen() -> Accessor* Accessor::gen()

C++ API removal:
- template<typename T = tvg::Paint> std::unique_ptr<T> cast(Paint* paint)
- template<typename T = tvg::Paint> std::unique_ptr<T> cast(Paint* paint)

76c1b20dee lottie: fix trim path regression
To avoid editing the trim path values provided

This caused an issue in the lottie animations when
the trim path is applied more than once. Now fixed.

1ee79a6c2a lottie: add 'tp' tag support
So far it hasn't been possible to specify
a matte layer - by default, it was the layer
above the calling layer. The 'tp' tag support
has been introduced, enabling referencing any
layer by its index.
In cases where the layer referencing the matte
was the first one, a segmentation fault was
observed. This issue has now been resolved.
