Shape's bbox represents only fill's render region.
Render region of fill and stroke is stored in SwTask.
This was visible while rendering shapes with a stroke -
fill was to big.

shape render region should be aligned with the
current shape bbox. this could bring the compact size
of the rendering region even shapes are not drawable.
During the stroke's outline calculation, the function
handling small cubics set all angles to zero. When
the cubic was small but not zero, this resulted in
incorrect outlines. Now such curves are ignored.

- OpenMp threads will be allocated alongside the TaskSculeduler::threads()
- Performance improved by 2x in a specific animation.
- Disable the thread feature in the Android build test due to system issues with OpenMP compilation.
Scene effects are typically applied to modify
the final appearance of a rendered scene,
such as adding a blur effect.
Each effect would have a different number of parameters
to control its visual properties. The Scene::push() interface
uses variadic arguments to accommodate various cases.
Users should refer to the SceneEffect API documentation
and pass the parameters exactly as required for the specific
effect type. For instance, GaussianBlur expects 3 parameters
which are:
- sigma(float)[greater than 0]
- direction(int)[both: 0 / horizontal: 1 / vertical: 2]
- border(int)[extend: 0 / wrap: 1]
- quality(int)[0 ~ 100]
and, scene->push(SceneEffect::GaussianBlur, 5.0f, 0, 0, 100);
New Experimental APIs:
- SceneEffect::ClearAll
- SceneEffect::GaussianBlur
- Result Scene::push(SceneEffect effect, ...);
Example:
- examples/SceneEffect

Separate clip function from the Composite()
clipping and composition can be used together.
This helps avoid the introduction of nested scenes
when composition and clipping overlap.
Deprecated:
- enum class CompositeMethod::ClipPath
- enum Tvg_Composite_Method::TVG_COMPOSITE_METHOD_CLIP_PATH
Experimental API:
- Result Paint::clip(std::unique_ptr<Paint> clipper)
- Tvg_Result tvg_paint_set_clip(Tvg_Paint* paint, Tvg_Paint* clipper)

Corrected the alpha interpolation order during blending.
This also corrected the hard mix blending result in the guitar sample.
issue: https://github.com/thorvg/thorvg/issues/2704
The limit on leftovers was too small, which became
noticeable for animations with trimming - currently
implemented with the dashing alg.
The limit has been increased.
The anti-aliased outline color was incorrectly blended
at the multiply option.
The fix can be observed in the example:
'examples/lottie/resourcesguitar.json'
in order to do this, RenderMehthod::blend() method introduced
`bool direct` for figuring out the intermediate composition.
Spec out this incomplete experimental feature,
this is a still promising one, we will reintroduce
this officially after 1.0 release

Lighten is applied, where multiple masks intersect,
the highest transparency value is used.
Darken is applied, where multiple masks intersect,
the lowest transparency value is used.
Experimental API:
- CompositeMethod::LightenMask
- CompositeMethod::DarkenMask

For a linear gradient defined by identical start and end
points, and for a radial gradient with a radius of 0,
the rendered shape should have the color of the last
specified color stop.
The documentation has been updated accordingly.
@Issue: https://github.com/thorvg/thorvg/issues/2582
The logic of interpretation of trimming start and
end values has been moved to the sw_engine,
so the values provided by the user are not modified.
No logical changes in the interpretation alg.
For pairs of trim's start/end values where the distance
between begin and end is >= 1, the entire stroke should
be drawn, but instead, nothing or only part is drawn. Fixed.
Stroke trim docs fixed.
The restriction of the 'length' of a linear gradient
to values greater than FLT_EPSILON was causing rendering
issues in cases where it was a valid gradient with well
defined dx and dy values.
