Dashed curves require greater precision in calculating
their lengths and while splitting Bezier curves.
Otherwise, it results in visual discrepancies compared
to the expected outcomes.
Approximate functions 'bezLengthApprox' and 'bezAtApprox'
used for calculations in the lottie loader.

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.

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, ..."

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
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.
