aa4c186cd2 lottie: introduced static layer cache. 
lottie builder doesn't need to rebuild the layer object
if it has no any animation frame data.

That case, we can cache the layer scene in order to reuse it.

Tested on local machine (single thread):
- Lottie: appx. 2ms enhanced.

0832a188fe animation/lottie: updated the frame count unit. 
replace the frame count unit from the int32_t to float
since animations could smoothly interpolate key-frames.

This notificably improve the animation smoothness in Lottie

Beta API changes:
Result Animation::frame(uint32_t no) -> Result Animation::frame(float no)
uint32_t Animation::curFrame() const -> float Animation::curFrame() const
uint32_t Animation::totalFrame() const -> float Animation::totalFrame() const

db1f171d2a wg_engine: Added ability to draw multiple linear gradient filled shapes 
[issues 1479: LinearGradient](thorvg#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);

    // gradient color stops
    tvg::Fill::ColorStop colorStops[2];
    colorStops[0] = {0, 0, 0, 0, 255};
    colorStops[1] = {1, 255, 255, 255, 255};
    // linear gradient
    auto fill = tvg::LinearGradient::gen();
    fill->linear(0, 0, 400, 400);
    fill->colorStops(colorStops, 2);
    // prepare rectangle
    auto shape1 = tvg::Shape::gen();
    shape1->appendRect(0, 0, 400, 400); //x, y, w, h
    shape1->fill(std::move(fill));
    canvas_wg->push(std::move(shape1));

    // gradient color stops
    tvg::Fill::ColorStop colorStops2[3];
    colorStops2[0] = { 0, 255, 0, 0, 255 };
    colorStops2[1] = { 0.5, 255, 255, 0, 255 };
    colorStops2[2] = { 1, 255, 255, 255, 255 };
    // linear gradient
    auto fill2 = tvg::LinearGradient::gen();
    fill2->linear(400, 200, 400, 600);
    fill2->colorStops(colorStops2, 3);
    // prepare circle
    auto shape2 = tvg::Shape::gen();
    shape2->appendCircle(400, 400, 200, 200); //cx, cy, radiusW, radiusH
    shape2->fill(std::move(fill2));
    canvas_wg->push(std::move(shape2));

    // gradient color stops
    tvg::Fill::ColorStop colorStops3[4];
    colorStops3[0] = { 0, 0, 127, 0, 127 };
    colorStops3[1] = { 0.25, 0, 170, 170, 170 };
    colorStops3[2] = { 0.5, 200, 0, 200, 200 };
    colorStops3[3] = { 1, 255, 255, 255, 255 };
    // linear gradient
    auto fill3 = tvg::LinearGradient::gen();
    fill3->linear(450, 600, 750, 600);
    fill3->colorStops(colorStops3, 4);
    // prepare ellipse
    auto shape3 = tvg::Shape::gen();
    shape3->appendCircle(600, 600, 150, 100); //cx, cy, radiusW, radiusH
    shape3->fill(std::move(fill3));
    canvas_wg->push(std::move(shape3));

    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);

43f45ebd65 sw_engine/math: fine-tuning optimization 
Try to minimize the use of sqrt() and arctan() calls
when possible. These calls can be relatively expensive
when accumulated within a single frame.

Also repalce the division with shift operation.
since split cubic function is one of the significant hot-spots
in the data processing, we could earn a noticable enhancement.

Tested on single thread local machine:

244e984df8 lottie/builder: Fix overlapped stroking outlines. 
Previously, the builder accumulated the outlines and fills
in one paint to reduce the rendering context.

However, this approach won't work for Lottie
if the resource contains multiple strokes with branched groups.

We should apply the optimization
only when the specified condition is satisfied.

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);
`
Still this feature is under the beta

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.
