5bdb585534 sw_engine: Rectified dash line drawing issue. 
Omit the dash line when its length falls below a minimal threshold.
This threshold is set to less than 0.0001 times the pixel size.

96f5f82050 sw_engine: retain the compositor cache memory 
The compositor memory is likely to be reused in the next frame.
To enhance performance, it is advisable to retain this memory by default.

We may consider introducing a cache policy interface in the Initializer.
This would allow users to manage the Canvas memory more effectively.

Anyhow, this improves the Lottie example performance by 10%

96e0794a67 wg_engine: introduced scene opacity 
[issues 1479: opacity](#1479)

Supported opacity value for scene

Usage example:

    //Create a Scene
    auto scene = tvg::Scene::gen();
    scene->opacity(100);

    //Prepare Circle
    auto shape1 = tvg::Shape::gen();
    shape1->appendCircle(400, 400, 250, 250);
    shape1->fill(255, 255, 0);
    shape1->opacity(100);
    scene->push(std::move(shape1));

    //Round rectangle
    auto shape2 = tvg::Shape::gen();
    shape2->appendRect(450, 100, 200, 200, 50, 50);
    shape2->fill(0, 255, 0);
    shape2->strokeWidth(10);
    shape2->strokeFill(255, 255, 255);
    scene->push(std::move(shape2));

    canvas->push(std::move(scene));

441542b272 common: STM32 portability enhancement 
Some systems such as micro-processor might not support
the thread feature on the system.

Enhance the portability by compiling the thorvg with toggling the
threading depepdency through the build option.

For this, thorvg newly introduced the internal Key/ScopedLock abstraction
for transparent thread-locking dependnecy.

To turn off the thread feature, please use the next build option:

$meson setup build -Dthreads=false ...

Note that, the thread feature is enabled in default.
Turning off the thread feature could reduce the binary size by 7kb.

af6969e15e wg_engine: introduced composition ability 
[issues 1479: Masking](#1479)

Supported composition methods:

    AlphaMask
    InvAlphaMask
    LumaMask
    InvLumaMask
    AddMask
    SubtractMask
    IntersectMask
    DifferenceMask

Usage example:

    //Solid Rectangle
    auto shape = tvg::Shape::gen();
    shape->appendRect(0, 0, 400, 400);
    shape->fill(0, 0, 255);

    //Mask
    auto mask = tvg::Shape::gen();
    mask->appendCircle(200, 200, 125, 125);
    mask->fill(255, 255, 255);        //AlphaMask RGB channels are unused.

    //Nested Mask
    auto nMask = tvg::Shape::gen();
    nMask->appendCircle(220, 220, 125, 125);
    nMask->fill(255, 255, 255);       //AlphaMask RGB channels are unused.

    mask->composite(std::move(nMask), tvg::CompositeMethod::AlphaMask);
    shape->composite(std::move(mask), tvg::CompositeMethod::AlphaMask);
    canvas->push(std::move(shape));

    //Star
    auto star = tvg::Shape::gen();
    star->fill(80, 80, 80);
    star->moveTo(599, 34);
    star->lineTo(653, 143);
    star->lineTo(774, 160);
    star->lineTo(687, 244);
    star->lineTo(707, 365);
    star->lineTo(599, 309);
    star->lineTo(497, 365);
    star->lineTo(512, 245);
    star->lineTo(426, 161);
    star->lineTo(546, 143);
    star->close();
    star->strokeWidth(30);
    star->strokeJoin(tvg::StrokeJoin::Miter);
    star->strokeFill(255, 255, 255);

    //Mask3
    auto mask3 = tvg::Shape::gen();
    mask3->appendCircle(600, 200, 125, 125);
    mask3->fill(255, 255, 255);       //AlphaMask RGB channels are unused.
    mask3->opacity(200);
    star->composite(std::move(mask3), tvg::CompositeMethod::AlphaMask);
    if (canvas->push(std::move(star)) != tvg::Result::Success) return;

38c625d070 renderer: enhanced shared surface handling with mutex implementation 
Introduced a dedicated mutex for each surface instance
to ensure safe sharing between the loader, renderer, and engine.

This enhancement allows for secure modification and access to bitmap data,
addressing potential concurrency issues.

Multiple Picture instances can now safely share a single loader instance,
optimizing performance.

This change builds upon the previous Loader Cache improvements:
