c8833e970d gl_engine: optimize framebuffer creation and save some runtime memory 
since the framebuffer will draw back to parent RenderPass, it can be
reused in next compose rendering.

So instead of create framebuffer every time when beginCompose is called, we
trying to reuse the framebuffer created before in the same stack level

f594806dd3 renderer/shape: Apply the magic number kappa to achieve rounded corners. 
The magic number kappa (0.552284), which is associated with the bezier curve,
has been introduced. This formula is supposed to be applied to the rounded corners
of the rectangle to ensure consistent drawing results.

f64ee28079 Loaders: Introduced a loader cache. 
The loader cache is applied to conserve memory.

If the input data is already present in loaders,
the loader cache will promptly return the active loader.

This results in a lot of memory savings for the duplicated resources.

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:

    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

    float dashPattern[2] = {20, 10};
    shape->strokeDash(dashPattern, 2);

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);

35b03c826e wg_engine: introduce a webgpu canvas(engine) 
WebGPU is a Render Hardware Interface built on top of the various APIs 
provided by the driver/OS depending on your platform. 

WebGPU exposes an API for performing operations, 
such as rendering and computation, on a Graphics Processing Unit.

WebGPU official documentation: https://www.w3.org/TR/webgpu/

The new engine type introduced: tvg::CanvasEngine::Wg

The new canvas type introduced: tvg::WgCanvas

Example:
$meson setup build -Dengines=wg_beta

`
    // 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);

    // ...

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

0a9d98ccfd sw_engine/stroke: enhanced the quality of the dash line corners. 
Previously, the engine didn't properly cover the dash line corner styles
because it considered a new line to start at the corner.

This update modifies the logic to recognize curved lines
as a single line, including the corners.

There may still be some quality issues,
but it's an improvement over the previous version.
