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

- refactored the Fill matrix to hold internal data statically.
- refactored for clean & neat the raster engine / svg loader logic.
API Modification:
- Matrix Fill::transform() const -> Matrix& Fill::transform() const

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, ...);

In cases where the distance between points is 0, further
processing of the points results in division by zero.
To avoid this check, we ensure that duplicate points are
not added during trimming.
Streaming model for massive vertex and index creations: minimize memory allocations, range checks and other conditions
Reduce number of segments length calculations (sqrt) and bbox (min and max).
Update distances and bboxes on a whole buffer and only if necessary. For shapes without strokes compute distances not necessary at all. bbox can be updated only on the final stage of geometry workflow, but not on the each stage.
Using stack memory instead of heap. its more cache friendly and did not fragment memory, faster memory allocations (weak place of realization)
Using cache for points distances and whole path length. Updates only if necessary
Validation of geometry consistency executes only on the final stage of path life cicle. It more friendly for data streaming: no any conditions and branches.
Using binary search for strokes trimming
Pre-cached circles geometry for caps and joints
Refactored strokes elements generation functions. Code is more readable and modifiable in general. Can be easily fixed if some geometry issues will be finded
