[issues 1479: lottie](#1479)
To optimize bled operations hardware pipeline blend stage are used for some blend methods:
BlendMethod::SrcOver
BlendMethod::Normal
BlendMethod::Add
BlendMethod::Multiply
BlendMethod::Darken
BlendMethod::Lighten
Other types compute shaders used
This correction addresses the drawing order of
objects when a group contains a TrimPath and
is merging shapes.
Additionally, the TrimPath method is can applied
to the engine to control the drawing behavior by

examples are not considered a feature of ThorVG;
hence, they are excluded from the src directory.
This change allows developers to concentrate more effectively
on the core ThorVG sources for practical usages.
this optimization nicely merges shapes
when a child group has a only (transformed) pathes.
this also fixes the following compatibility issue nicely.

When finding the 'nodeFrom' referenced by `<use>`,
if it is the parent, it is not referenced.
https://www.w3.org/TR/SVG2/struct.html#UseElement
Specification:
If the referenced element is a (shadow-including) ancestor
of the ‘use’ element, then this is an invalid circular reference
and the ‘use’ element is in error.

removed unused static condition.
static was prepared for optimization,
but not used at all.
we will revisit this later when time permits.

When lottie is broken and provides invalid gradient, the program crashes in segmentation fault.
At that time, in the `populate` function, `ColorStop& color` doesn't have `input` but tries to use it.
Added checking nullptr logic. The function `populate` will not proceed and return 0 in that case.

There are differences in behavior compared to the SVG spec,
especially when consecutive line drawings occur without a moveTo command
following a closePath command.
Actually, thorvg didn't care the behavior in that scenario,
this update ensures the scenario is handled correctly
to align with the SVG specification.

Slot overriding tries to set property via the `LottieObject`. It potentially causes unexpected changes.
Revised the `override` function. The purpose of this patch is to aim atomic property to be overriden.
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)`

When image data fails to load or image parsing fails,
the id is leaked without being assigned to the name.
To prevent that, free id value when obj is nullptr.

* Support rendering Gradient in path Stroke mode
* Fix GlStencilCoverTask not support even-odd fill rule
* Make GlStencilCoverTask can discard overlapped area during stroke

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.

This commit addresses an issue where paints lost their
composition context when drawings occurred without any updates.
Now, paints will consistently retain the composition context,
ensuring accurate rendering.
