The text stroke's 'of' property determines whether
the stroke appears above (true) or below (false)
the fill.
Previously, it was incorrectly used to decide whether
the stroke would render.
@Issue: https://github.com/thorvg/thorvg/issues/3126
After the stroke clipper is introduced, using clipping
requires ensuring that clipping is based on fill rather
than on stroke. Fixed now.

- Allow the masking data even though they were mask None mode.
Those will be used by the layer stroke effect.
- Fixed masking Offset to apply to all masking chains.
- Optimized fast track masking with resolving the opaicty condition.
- Clean up the overall code.
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.
- Enhanced Scene management to provide users with more control.
- Scenes now support adding specific scenes at defined positions and removing them as needed.
- Ensure safe access to Canvas, Scene paints() by adding const specifiers.
- Removed virtual specifier for the canvas primitive apis.
- Introduced a nested scene in the canvas to remove logic duplication.

Reverted commit db800c8d45,
which introduced another regression that omitted support
for multiple image asset references.
Updated the data of active images in the pooler
within the override() function to resolve the issue.
Change in the algorithm for selecting characters included
in the range selector. This is the first step towards adding
support for maxAmount, smoothness, and easing.

Remove the requirement for unique_ptr in the function prototypes.
This change will simplify the API usage, making it more streamlined
and user-friendly. However, memory management will now be the
responsibility of the user.

issue: https://github.com/thorvg/thorvg/issues
Since the translate API was used while text updating,
the subsequent range selector transformations gets overwritten
when updating the shape (scale and rotate, adding another
translation will persist). This caused unexpected results.
Fixed by using the transform API when additional transformations
are needed - also fixes applying more than one range selector.
According to tests in AE, the offset direction should
not depend on the direction of the shape. A positive
offset value expands the shape, while a negative value
contracts it. Fixed.
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

Use a clipper instead of masking when the condition is satisfied.
Generally, clipping is cheaper than masking in fps & memory usage.

Improving text render compatibility by fixing wrong Text Range.
When lottie doesn't have `end` prop in the range, system must ignore condition regarding to `end`.
The original logic unintentionally swaps `start` and `end` prop, because `end` is the zero in this case. Then the text range animation behaves the opposite.
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)
Issue: https://github.com/thorvg/thorvg/issues/1496
on each parse, if the `randomize` is enabled,
the start and end of the Text Range are redefined
with the same gap as the original range.

Added support for Text Based of Text Range Selector, by processing further properties:
2. Character Excluding Spaces
3. Words
4. Lines

Due to the lack of an analytical solution for Bezier
curves offsetting, a simple and computationally cheap
approximation has been implemented. The algorithm shifts
the segments connecting control points and determines
new points based on their intersections.
