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.
The color input will contain at least colorStops.count * 4
elements (not including alpha). Since the alpha offset values
don't have to much colorStops, estimation is used.
For long Bezier curves compared to the offset value,
the offsetting algorithm caused deformation. The problem
became evident after adding mask extension, as the simple
shapes defined there are based on Bezier curves rather
than as shapes like a circle/rect/etc, which is the case
for the offset. Now 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

When populating the gradient, the color/alpha should
be assigned the first possible value from the provided
ones, rather than the default value of 255.
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)

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

According to the definition of trim path elements,
the begin and end values are specified as percentages
in the range of 0-100% (this is also confirmed by AE,
where it's not possible to exceed this range).
Added clamping to align with spec.
To avoid editing the trim path values provided
by the user, the logic for their interpretation
was moved from the API to the renderer (7c87d8e).
This caused an issue in the lottie animations when
the trim path is applied more than once. Now fixed.

- Prevent expression processing if a property fails to parse.
- Fixed an incorrect usage of JerryScript.
This is a hotfix to address expression-related crashes.
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.
