0665837899 gif/encoder: fixed memory violation. 
There was an invalid palette data access
when no frame data had been changed, detected by memory sanitizer.

c5b642e3e7 wg_engine: introduced images drawing support 
[issues 1479: pictures](https://github.com/thorvg/thorvg/issues/1479)

    auto picture = tvg::Picture::gen();
    picture->load("images/test.png");
    picture->translate(0, 0);
    picture->size(100, 100);
    picture->opacity(255);
    canvas->push(std::move(picture));

b87bb2b1a0 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.

bad02c7de0 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();

a20216045a 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);
