We have improved the functionality to manage the memory pool safely,
by figuring out the current working threads. Users no longer need to
manually configure memory pool management, and the related APIs
have been removed.
API Removals:
- Result SwCanvas::mempool(MempoolPolicy policy)
- enum SwCanvas::MempoolPolicy
- Tvg_Result tvg_swcanvas_set_mempool(Tvg_Canvas* canvas, Tvg_Mempool_Policy policy)
- enum Tvg_Mempool_Policy

Changed the unit of the segment from a normalized value to frame numbers,
ensuring alignment with other frame control interfaces.
Note that This change may break backward compatibility.

The Tritone effect maps the scene's shadows, midtones, and highlights
to three specific colors, allowing for more complex and artistic color grading.
Applied Tritone Formula:
if (L < 0.5) Result = (1 - 2L) * Shadow + 2L * Midtone
else Result = (1 - 2(L - 0.5)) * Midtone + (2(L - 0.5)) * Highlight
Where the L is Luminance.

The Tint effect in ThorVG is used to modify the overall color tone of a scene.
It works by blending a specified tint color with the existing colors of the scene.
This effect is useful for color grading, mood changes, or applying thematic filters
to vector graphics and animations.
Applied the equation is:
Result = (1 - L) * Black + L * White, where the L is Luminance.

ThorVG pImpl idiom caused internal data to be scattered
across hierarchical classes. This refactoring consolidates
the data by inheriting pImpl internally, reducing memory
allocation counts and eliminating unnecessary strategy methods.
Added a `clear` parameter to Canvas::draw(), allowing users to decide
whether to clear the target buffer before drawing.
To remove the paints from a canvas, please use Canvas::remove()

- prevent dangling instances in failure scenarios by utilizing a reference counter.
- update the test suite to treat null pointer arguments as invalid argument failures.

responsibility of the user.

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)

Spec out this incomplete experimental feature,
this is a still promising one, we will reintroduce
this officially after 1.0 release
size: -2kb
issue: https://github.com/thorvg/thorvg/issues/1372
The current Paint::bounds(transform=true) returns the coordinates
of the paint in its local coordinates after transformation.
However, it did not convert the origin to the world coordinate.
This is problematic when the user wants to determine
the paint's position and size with the origin being the canvas.
Specifically, this matters that when the paint is belonged
to a certain scene.
Now, the bounds() method returns the coordinates
of the paint's bounding box with the corrected world space.
User can figure out the actual boundary within the painted result.
Remark that, this may break the functional behavior compatibility.
