6944633f41 lottie: Improve feature coverage by correctly handling XOR shapes 
XOR when the shape's direction property is set to a value of 2.
Currently, the direction property is expected to have
either 1 for clockwise or 3 for counterclockwise orientation.

Just found out the number 2 use-case...

71cc7c2e30 lottie: Fixed the issue with gradient filling. 
Previously, multiple gradients within a single group
couldn't be accounted for during rendering.

This fix addresses the scenario by fragmenting the rendering context.

There are some matting masking bugs observed,
Reverted the commit. We will revisit it later.

commit d37c500262
Author: Hermet Park <hermet@lottiefiles.com>
Date:   Wed Oct 25 18:55:05 2023 +0900

    lottie: introduced static layer cache.

    lottie builder doesn't need to rebuild the layer object
    if it has no any animation frame data.

    That case, we can cache the layer scene in order to reuse it.

    Tested on local machine (single thread):
    - Lottie: appx. 2ms enhanced.
    - Binary: +204

25a1321243 common: stroke dash offset support with new apis. 
This change just allows users to use the offset of the stroke dash.
Actually feature enhacement has been introduced by
478e45f9f3.

@APIs:
uint32_t Shape::strokeDash(const float** dashPattern) ->
uint32_t Shape::strokeDash(const float** dashPattern, float* offset = nullptr)

Result Shape::strokeDash(const float* dashPattern, uint32_t cnt) ->
Result Shape::strokeDash(const float* dashPattern, uint32_t cnt, float offset = 0.0f)

Tvg_Result tvg_shape_set_stroke_dash(Tvg_Paint* paint, const float* dashPattern, uint32_t cnt) ->
Tvg_Result tvg_shape_set_stroke_dash(Tvg_Paint* paint, const float* dashPattern, uint32_t cnt, float offset)

Tvg_Result tvg_shape_get_stroke_dash(const Tvg_Paint* paint, const float** dashPattern, uint32_t* cnt) ->

This notificably improve the animation smoothness in Lottie

625c2405fc lottie/builder: Fix overlapped stroking outlines. 
Previously, the builder accumulated the outlines and fills
in one paint to reduce the rendering context.

However, this approach won't work for Lottie
if the resource contains multiple strokes with branched groups.

We should apply the optimization
only when the specified condition is satisfied.
