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.
This utility method allows access to a specific paint instance
by its unique identifier.
Experimental API:
- const Paint* Picture::paint(uint32_t id)
- const Tvg_Paint* tvg_picture_get_paint(Tvg_Paint* paint, uint32_t id)
This function computes a unique identifier value based on the provided string.
You can use this to assign a unique ID to the Paint object.
Experimental APIs:
- uint32_t Accessorr::id(const char* name)
- uint32_t tvg_accessor_id(const char* name)
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.

The logic of interpretation of trimming start and
end values has been moved to the sw_engine,
so the values provided by the user are not modified.
No logical changes in the interpretation alg.
For pairs of trim's start/end values where the distance
between begin and end is >= 1, the entire stroke should
be drawn, but instead, nothing or only part is drawn. Fixed.
Stroke trim docs fixed.
This corrects the return value to Result::InsufficientCondition
when a custom transform is applied.
Additionally, unnecessary x and y member fields have been removed.
There was a typo in the name (tvg_canvas_est_viewport),
which made it seem like it was missing. The correctly
named API has already been added, so this one can be
removed.
NonSupport indicates unsupported options due to disabled features
or lack of system support. InvalidArgument indicates the case
such as incorrect parameter values.
The functions setting stroke's features always
returned a true. Returnig a boolen was a remnant
from a previous implementation. Since now they
never return false, they can be void functions.
The APIs description has been corrected.

Currently, tvg ignores the frame value if the difference
is less than 0.001. In most cases, updating the frames
when the change is less than 1ms is just an unnecessary
burden on the system.
Instead, this ensures that the perfect last frame is reached.

re-implement the gif conversion function with the correct approach.
The input data is not reusable as it undergoes modifications during parsing.
To address this, the function now creates a backup of the original data for use in GIF conversion.
This also resolves issues where the GIF viewport was incorrectly matched.
This implementation may be revisited upon
the availability of Animation::duplicate().
Implemented the ability to revert Lottie slots by calling override with nullptr.
This functionality allows for the complete reversal of applied slots.
usage:
- `animation->override(nullptr)`

The previous loader cache mechanism encountered a problem
when the user changed the content of the cached data.
In such cases, a new request would not be processed
because the renderer would use the previously cached content.
So far, the TVG cache mechanism utilizes a pointer hash key
for the fastest hashing mechanism available.
One limitation is that it assumes the address is unique for the data.
To resolve this, we modified the caching policy.
Now, the renderer will not cache copied data;
it will only cache the given data when it is deemed shareable.

these experimental apis are allowed to use
when the lottie loader is enabled.
APIs:
- Tvg_Animation* tvg_lottie_animation_new()
- Tvg_Result tvg_lottie_animation_override(Tvg_Animation* animation, const char* slot)
