29b5bc372d lottie/loader: Corrected an issue with the return value when loading fails. 
Previously, Picture::load(const char* data, uint32_t size, const std::string& mimeType, bool copy = false)
would return 'Success' even when the data is invalid.

This issue only occurred when the number of threads is set to 0.

52eca9630c Added ability to draw solid strokes with dashes 
[issues 1479: Shape](https://github.com/thorvg/thorvg/issues/1479)

In order to build you need third party libraries. Before you start please read this: [LearnWebGPU](https://eliemichel.github.io/LearnWebGPU/getting-started/hello-webgpu.html)

Usage example:

    // init glfw
    glfwInit();

    // create a windowed mode window and its opengl context
    glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
    GLFWwindow* window = glfwCreateWindow(800, 800, "WebGPU base app", nullptr, nullptr);

    // get window size
    int width{}, height{};
    glfwGetWindowSize(window, &width, &height);

    // init engine webgpu
    tvg::Initializer::init(tvg::CanvasEngine::Wg, 0);

    // create wg canvas
    auto canvasWg = tvg::WgCanvas::gen();
    canvas_wg->target(glfwGetWin32Window(window), width, height);

    //Test for Stroke Dash for Arc, Circle, Rect
    auto shape = tvg::Shape::gen();
    shape->appendArc(70, 600, 160, 10, 30, true);
    shape->appendCircle(70, 700, 20, 60);
    shape->appendRect(130, 710, 100, 40);
    shape->strokeFill(255, 0, 0);
    shape->strokeWidth(5);
    shape->strokeJoin(tvg::StrokeJoin::Round);
    shape->strokeCap(tvg::StrokeCap::Round);
    float dashPattern[2] = {20, 10};
    shape->strokeDash(dashPattern, 2);
    if (canvas_wg->push(std::move(shape)) != tvg::Result::Success) return;

    while (!glfwWindowShouldClose(window)) {
        // webgpu
        canvas_wg->draw();
        canvas_wg->sync();

        // pull events
        glfwPollEvents();
    }

    // terminate engine and window
    tvg::Initializer::term(tvg::CanvasEngine::Wg);
    glfwDestroyWindow(window);
    glfwTerminate();

d03bf7a089 saver GifSaver: Introduce GifSaver for animation 
Add save() API that takes tvg::Animation as a parameter.
This API uses gif.h to create each animation frame as a gif frame.
Gif creation do not support threads because they must be added sequentially.
Please see example/GifSaver.cpp

ex)
auto animation = tvg::Animation::gen();
auto picture = animation->picture();
picture->load(EXAMPLE_DIR"/walker.json");
auto saver = tvg::Saver::gen();
saver->save(std::move(animation), EXAMPLE_DIR"/test.gif");
saver->sync();

New API:
Result Saver::save(std::unique_ptr<Animation> animation, const std::string& path, uint32_t quality = 100, uint32_t fps = 0);
