Each group must determine the stroking rendering contexts
and assess whether context switching has occurred.
Migrate the sequence from the root layer to all groups.
Some systems such as micro-processor might not support
the thread feature on the system.
Enhance the portability by compiling the thorvg with toggling the
threading depepdency through the build option.
For this, thorvg newly introduced the internal Key/ScopedLock abstraction
for transparent thread-locking dependnecy.
To turn off the thread feature, please use the next build option:
$meson setup build -Dthreads=false ...
Note that, the thread feature is enabled in default.
Turning off the thread feature could reduce the binary size by 7kb.

the bug was introduced in 9bf8bb018d.
Migrated the circle commands to the rectangle, which is currently necessary.
Retained the previous circle commands for backward compatibility.
enable exceeding the range of normalized values in time remapping.
the issue came from a misunderstanding of the lottie spec.

Adjusted the path's start point to 90 degrees
to align the origin consistently with other path commands.
No compatibility issue, this only could affect the trimpath effects.
Introduced a dedicated mutex for each surface instance
to ensure safe sharing between the loader, renderer, and engine.
This enhancement allows for secure modification and access to bitmap data,
addressing potential concurrency issues.
Multiple Picture instances can now safely share a single loader instance,
optimizing performance.
This change builds upon the previous Loader Cache improvements:

Applied 2 more internal LoaderMgr interfaces for
gobally manage the font data resources.
The next function is introduced for lookup the existing loader
with the font name (key)
- static LoaderMgr::LoadModule* loader(const char* key);
The next function is introduced to free the existing loader
with the loader source(file path)
- static bool retrieve(const string& path);
Additionally implements the base loader to bind the ttf loader.
ttf is an industry standard format that is the most widely used
in the products. Now thorvg supports the basic features of
the font to supplement the text drawing.
The implementation is followed the ttf spec,
the covered features are:
- horizontal layouting with kerning.
- utf8 -> utf32 converted glyph drawing.
To use the feature, please enable ttf loader:
$meson -Dloaders="ttf_beta, ..."
