previously, the bounding box calculation was simply
determined by comparing all the points, which led to
incorrect sizing due to Bezier control points.
Now, it accurately computes the curve boundary,
properly addressing this issue.
implemented an aggressive culling strategy to eliminate
unnecessary renderings if the rendering visuals were hidden
by other overlaid opaque fills or strokes
this pretty improves the performance for those scenarios
when rendering sequences are fragmented by fills/strokes.
Performance has been improved ~7% with those cases
Generating the outline may return false, e.g., if the shape
is completely trimmed. If such a shape was used as a clip,
an attempt to generate 'rle' will still be made. In such a case,
a crash will occur because the outline is nullptr.
Enable default font compression to reduce WASM size.
The LZSS algorithm is a simple compression method with advantages in decompression performance.
Font data is optimized without external compression dependencies, reducing the embedded font size to 9KB (-40%).
While dashing, changing the path command each time caused
a new 'move to' command to be added, even when dash segments
across different path commands should have been connected.
@Issue: https://github.com/thorvg/thorvg/issues/3231
The differences resulted from discrepancies between
the engines in applying equality or inequality signs
and in using different precision levels when determining
the dash remainder when transitioning to a new path
command.

Until now the fill's trimming was not supported,
which allowed masks to function correctly. Introducing
trimming for the entire shape caused the mask to be trimmed
as well, leading to incorrect results.

Until now, only stroke trimming was possible,
but the Lottie standard requires support for
trimming both (if present), stroke and fill.
This commit changes the API behavior.

A JavaScript code line may return undefined, but this should not be treated as an error.
For example, consider the following two lines of code:
- `var $bm_rt = 30` (Statement) → result: `undefined`
- `$bm_rt = 30` (Expression) → result: `30`
Both lines execute the same operation, but the JavaScript interpreter (REPL JS) evaluates them differently.
Therefore, an evaluation result of undefined should not be blocked, as it does not indicate a failed code execution.
Load default font data during initialization. This enables the web system to load when the system font cannot be used.
Added a binary-embeddable font file resource. This file has quite small size while containing essential glyphs.

Before the C++ compiler couldn't decide the template of std::min (that happen if `int` type is not an `int32_t`), so explicitly changing all types to int32_t fixes this.
Support the bindings to be more integrable with a system's coherent memory management.
Pleaes note that thorvg now only allow the desinated memory allocators here:
malloc -> tvg::malloc
calloc -> tvg::calloc
realloc -> tvg::realloc
free -> tvg::free
