added 2 more APIs for user convenience to allow backtracking tree traversal.
API Additions:
- const Paint* Paint::scene() const
- const Tvg_Paint* tvg_paint_get_scene(const Tvg_Paint* paint)
- Enhanced Scene management to provide users with more control.
- Scenes now support adding specific scenes at defined positions and removing them as needed.
- Ensure safe access to Canvas, Scene paints() by adding const specifiers.
- Removed virtual specifier for the canvas primitive apis.

- prevent dangling instances in failure scenarios by utilizing a reference counter.
- update the test suite to treat null pointer arguments as invalid argument failures.
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:

issue: https://github.com/thorvg/thorvg/issues
deprecate the `identifier()` APIs by replacing them with `type()`.
ThorVG is going to introduce an instance `id()`,
and this could be confused with the `identifier()` methods.
with this new type() method can reduce the memory size
by removing unncessary type data.
New Experimental C APIs:
- enum Tvg_Type
- Tvg_Result tvg_paint_get_type(const Tvg_Paint* paint, Tvg_Type* type)
- Tvg_Result tvg_gradient_get_type(const Tvg_Gradient* grad, Tvg_Type* type)
New Experimental C++ APIs:
- Type Paint::type() const
- Type Fill::type() const
- Type LinearGradient::type() const
- Type RadialGradient::type() const
- Type Shape::type() const
- Type Scene::type() const
- Type Picture::type() const
- Type Text::type() const
Deprecated C APIs:
- enum Tvg_Identifier
- Tvg_Result tvg_paint_get_identifier(const Tvg_Paint* paint, Tvg_Identifier* identifier)
- Tvg_Result tvg_gradient_get_identifier(const Tvg_Gradient* grad, Tvg_Identifier* identifier)
Deprecated C++ APIs:
- enum class Type
- uint32_t Paint::identifier() const
- uint32_t Fill::identifier() const
- static uint32_t Picture::identifier()
- static uint32_t Scene::identifier()
- static uint32_t Shape::identifier()
- static uint32_t LinearGradient:identifier()
- static uint32_T RadialGradient::identfier()
Removed Experimental APIs:
- static uint32_t Text::identifier()

This change introduces the CanvasEngine::All type to automatically
initialize the engines available on the current system.
These revisions improve the usability of these APIs.
Addtions:
- enum class CanvasEngine::All
Modifications:
- Result Initializer::init(CanvasEngine engine, uint32_t threads) ->
Result Initializer::init(uint32_t threads, CanvasEngine engine = tvg::CanvasEngine::All)
These new apis would enable users to easily modify the motion scene,
The data structure of the paints has been changed from an array to a list.
@APIs:
std::list<Paint*>& Canvas::paints() noexcept;
std::list<Paint*>& Scene::paints() noexcept;
@Deprecated:
Result Canvas::reserve(uint32_t size) noexcept;
Result Scene::reserve(uint32_t size) noexcept;
@Issue: https://github.com/thorvg/thorvg/issues/1203
Split some tests into SECTIONs based on their type.
This improves the readability of TC.
And developer can run test in SECTION unit.
ex)
./build/test/tvgUnitTests "Pushing Paints Into Scene" -c "Pushing Null Pointer"
tests is now officially placed in src/examples,
default is turned off, only necessaries turn it on.
ex) meson . build -Dexamples=true
+ this examples are required efl 'elementary' package.
initialization interfaces has been changed for threads count.
if you want to set concrete threads count by system, please specify thread count with it.
std threads:
tvg::Initializer::init(tvg::CanvasEngine::Sw, std:🧵:hardware_concurrency());
if your system provides designed threads info, you can use it.
efl:
tvg_engine_init(TVG_ENGINE_SW, eina_cpu_count());
I recommend to avoid max threads usage for better performance.

We can use RGBA colorspace rather ARGB for pixel data.
This would be better for many rendering system,
since it's more widely preferred than ARGB including opengl.

Scene is a group(list) of paints.
This class is designed for vector data set which is prepared before canvas.
If a set of vector data is loaded from other resources such as files,
they can construct these data set using Scene.
This then can be pushed into canvas as one completed image.
Scene is supposed to be used in svg loading and storing to tvg specific data format(tvg)
Change-Id: Ie2ffebf74e79c59d99a77880630a54b6baad7eec
PaintNode -> Paint
ShapeNode -> Shape
SceneNode -> Scene
We can keep clean and neat shorter names.
