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
