10e566edc1 sw_engine: fixed a bug where strokes were not showing. 
Basic shapes were trimmed entirely when they were outside of the canvas,
even if they had a big enough stroke to be partially on the canvas.

This fixes the issue.

ba46790b78 lottie/parser: Fix the shapes parsing logic. 
Currently, it assumes "ty":"gr" for the related shapes children,
which can be skipped since the children will be in the "it" scope.

Some Lottie data is missing the "ty":"gr" field,
and ThorVG couldn't display the content properly.
It can ignore it with the context understanding.

Previously, Picture::load(const char* data, uint32_t size, const std::string& mimeType, bool copy = false)

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();
