Since we've separated ClipPath and Masking,
Masking now has a distinct and independent purpose.
API Modification:
- enum class CompositeMethod -> enum class MaskMethod
- Result Paint::composite(std::unique_ptr<Paint> target, CompositeMethod method) -> Result Paint::mask(std::unique_ptr<Paint> target, MaskMethod method)
- CompositeMethod Paint::mask(const Paint** target) const -> MaskMethod Paint::mask(const Paint** target) const
issue: https://github.com/thorvg/thorvg/issues/1372
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.

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 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

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 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.
@Issue: https://github.com/thorvg/thorvg/issues/2582
deprecate the `identifier()` APIs by replacing them with `type()`.
ThorVG is going to introduce an instance `id()`,
and this could be confused with the `identifier()` methods.
with this new type() method can reduce the memory size
by removing unncessary type data.
New Experimental C APIs:
- enum Tvg_Type
- Tvg_Result tvg_paint_get_type(const Tvg_Paint* paint, Tvg_Type* type)
- Tvg_Result tvg_gradient_get_type(const Tvg_Gradient* grad, Tvg_Type* type)
New Experimental C++ APIs:
- Type Paint::type() const
- Type Fill::type() const
- Type LinearGradient::type() const
- Type RadialGradient::type() const
- Type Shape::type() const
- Type Scene::type() const
- Type Picture::type() const
- Type Text::type() const
Deprecated C APIs:

- Tvg_Result tvg_paint_get_identifier(const Tvg_Paint* paint, Tvg_Identifier* identifier)
- Tvg_Result tvg_gradient_get_identifier(const Tvg_Gradient* grad, Tvg_Identifier* identifier)
Deprecated C++ APIs:

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:

Streamlining computations with floating-point operations in rotation
thereby improving 'thorvg' speed.
Also use the well-optimized posix math functions instead of
custom math.
Test on my local machine.
Lottie: -0.008s (0.073 -> 0.065)
Performance: -0.0013s (0.0154 -> 0.0141)

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.
