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) issue: https://github.com/thorvg/thorvg/issues
