When json file is invalid in the parser,
the LottieComposition object is not released and the parse() returns false.
To prevent memory leaks, free the memory before returning false.

Enhances the portability of the TTF loader on UWP platforms
by implementing an alternative file loading mechanism.
This is designed to support environments where the file mapping
feature is not available, ensuring wider compatibility and reliability
in file handling.

The lottie format defines the starting point for
drawing rectangles and ellipses differently than
the API available in the TVG. In the case of using
dashes or trim paths, this leads to discrepancies.
Therefore, when using the lottie builder, internal
functions for appending rectangles and circles are
utilized.

This class extends the Animation and serves advanced Lottie features.
It's designed to separately have Lottie Animation's unique specs.
For now, this will have Slot overriding feature,
you can include <thorvg_lottie.h> for its extensive features.
@APIs:
- Result LottieAnimation::override(const char* slotJson) noexcept;
- static std::unique_ptr<LottieAnimation> LottieAnimation::gen() noexcept;
@Issue: https://github.com/thorvg/thorvg/issues/1808
Internal model and parser modifications have been made
to parse "sid" and retrieve their data into the LottieComposition.
This will enable dynamic changes to the following Lottie objects:
The slot feature will encompass these properties:
- LottieSolidStroke
- LottieSolidFill
- LottieGradientStroke
- LottieGradientFill
- LottieTextDoc"

To ensure consistent properties, `LottieSolid` has been defined.
Both `LottieSolidStroke` and `LottieSolidFill` can be typecasted to the `LottieSolid`.
Improve parenthesis checking and space checking.
- There must be only one pair of parentheses.
- There cannot be spaces(and ') between id strings.

Dashed curves require greater precision in calculating
their lengths and while splitting Bezier curves.
Otherwise, it results in visual discrepancies compared
to the expected outcomes.
Approximate functions 'bezLengthApprox' and 'bezAtApprox'
used for calculations in the lottie loader.

enhance decoding efficiency by determining the desired canvas format
during image loading. This allows loaders to preemptively decode
the image in the specified format, to not convert the format again.
Previously, the Lottie parser expected a specific parsing order:
font followed by glyph, for optimal data processing.
However, since this order is not guaranteed,
we have revised the parsing logic to accommodate any order.
The three specifications below apply.
Specification: https://www.w3.org/TR/SVG/paths.html#ArcOutOfRangeParameters
-
If the endpoint (x, y) of the segment is identical to the current point
(e.g., the endpoint of the previous segment),
then this is equivalent to omitting the elliptical arc segment entirely.
-
If either rx or ry is 0, then this arc is treated
as a straight line segment(a "lineto") joining the endpoints.
-
If either rx or ry have negative signs, these are dropped;
the absolute value is used instead.
resolved a corner case where assets were being attached
multiple times during scene building. This issue was causing
a significant performence drop in image animation
in certain scenarios.
