273850a972 renderer/shape: Apply the magic number kappa to achieve rounded corners. 
The magic number kappa (0.552284), which is associated with the bezier curve,
has been introduced. This formula is supposed to be applied to the rounded corners
of the rectangle to ensure consistent drawing results.

ff6ea4b6c4 Loaders: Introduced a loader cache. 
The loader cache is applied to conserve memory.

If the input data is already present in loaders,
the loader cache will promptly return the active loader.

This results in a lot of memory savings for the duplicated resources.

binary diff: -400 bytes

e89eb09a33 common/inlist: added a inline list data structure. 
Inline lists mean that their nodes' pointers are part of the same memory as the data.
This has the benefit of fragmenting memory less and avoiding node->data indirection.

132be91de4 lottie/loader: support external image from memeory lottie 
I've added new parameter, const string& resourcePath, to load external image on lottie.

Result load(const char* data, uint32_t size, const string& mimeType, bool copy, const string& resourcePath)

Note: tvgLoadModule will have new overrided method `open`, not to effect to other changes except animation.

4c95ed3e51 Lottie/builder: revert a static cache optimization. 
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

548962f5f8 apis/engines: Revise the clear() buffer behavior. 
ThorVG has offered an option to clear the buffer since version 1.0.
This is essential when users utilize the canvas target buffer
with the main render target. They share the buffer
and need to draw contents onto the existing contents.

API:
Result Canvas::clear(bool free = true)
-> Result Canvas::clear(bool paints = true, bool buffer = true)

Tvg_Result tvg_canvas_clear(Tvg_Canvas* canvas, bool free);
-> Tvg_Result tvg_canvas_clear(Tvg_Canvas* canvas, bool paints, bool buffer);

10e566edc1 sw_engine: fixed a bug where strokes were not showing.

even if they had a big enough stroke to be partially on the canvas.

ba46790b78 lottie/parser: Fix the shapes parsing logic. 
Currently, it assumes "ty":"gr" for the related shapes children,
which can be skipped since the children will be in the "it" scope.

Some Lottie data is missing the "ty":"gr" field,
and ThorVG couldn't display the content properly.
It can ignore it with the context understanding.
