certain systems, may not support file I/O operations.
ThorVG should provide users with an option to configure
builds according to their requirements.
This ensures that file I/O calls are avoided,
preventing potential crashes.
Please use the meson '-Dfile=true/false' option for this.
Please note that "THORVG_FILE_IO_SUPPORT" might be expected
for your thorvg manual build.

If a Meson option is typed as `boolean`, the `get_option` returns a
boolean, and comparing it with `true` is redundant. Meson also errors if
you try to compare across types, so it couldn't _not_ be a boolean.
Also, Meson is not C, so no need for parentheses around `if` conditions.
In case of modern systems, size is not a big problem,
so we turn the optimization option to default
for better performance.
FPS: ~20% enhanced
Size: ~25% increased
Note that this doesn't affect to the web player.
The ThorVG OpenGL/ES engine has been stabilized and improved
significantly. Now, as a graphics engine, its drawing features
are quite functional. It is time to officially release the
engine and maintain it in the release process.
Thanks @Ruiwen for going above and beyond!

this commit introduces an additional build options:
- lottie expressions: this advanced feature in Lottie can
significantly increase binary size. Users now have the option
to enable or disable it based on their requirements.
Note that, this change introduces one config definitions:
- THORVG_LOTTIE_EXPRESSIONS_SUPPORT
the WIN32_LEAN_AND_MEAN definition will remove the unused
features in windows.h that helps to improve the build-speed
as well as fixing the issue.

introduced the JerryScript engine to interpret Lottie
expressions, enhancing the capability to support runtime
programmable animation logic within Lottie expressions
spec. This feature, based on js scripting, represents
the most complicated addition to the Lottie spec so far.
ThorVG probably could includes an option to toggle
this feature at build time, allowing for customizable user
configurations according to specific requirements.
removed unused features for the optimal size:
- DEBUGGER
- MEM_STATS
- SNAPSHOT
- BUILTIN_JSON
- BUILTIN_PROXY
- BUILTIN_REFLECT
- BUILTIN_ATOMICS
- PROMISE_CALLBACK
- MODULE_SYSTEM
- SYSTEM_PORT
This is an experimental version.
Please manually enable the 'lottie-expressions' in meson.build
when you wish to use it.
See: https://jerryscript.net/
Selecting a tool without choosing the required tools
resulted in a usage error. Now, the activation
of the appropriate saver/loader for a given tool
is enforced.
Note that this change renames the Meson option from 'vector' to 'simd',
separates the NEON types into 'neon-arm' and 'neon-aarch',
and designates the 'mfpu' option solely for 'neon-arm'.
examples are not considered a feature of ThorVG;
hence, they are excluded from the src directory.
This change allows developers to concentrate more effectively
on the core ThorVG sources for practical usages.
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, ..."

Add save() API that takes tvg::Animation as a parameter.
This API uses gif.h to create each animation frame as a gif frame.
Gif creation do not support threads because they must be added sequentially.
Please see example/GifSaver.cpp
ex)
auto animation = tvg::Animation::gen();
auto picture = animation->picture();
picture->load(EXAMPLE_DIR"/walker.json");
auto saver = tvg::Saver::gen();
saver->save(std::move(animation), EXAMPLE_DIR"/test.gif");
saver->sync();
New API:
Result Saver::save(std::unique_ptr<Animation> animation, const std::string& path, uint32_t quality = 100, uint32_t fps = 0);

WebGPU is a Render Hardware Interface built on top of the various APIs
provided by the driver/OS depending on your platform.
WebGPU exposes an API for performing operations,
such as rendering and computation, on a Graphics Processing Unit.
WebGPU official documentation: https://www.w3.org/TR/webgpu/
The new engine type introduced: tvg::CanvasEngine::Wg
The new canvas type introduced: tvg::WgCanvas
Example:
$meson setup build -Dengines=wg_beta
`
// init engine webgpu
tvg::Initializer::init(tvg::CanvasEngine::Wg, 0);
// create wg canvas
auto canvasWg = tvg::WgCanvas::gen();
canvas_wg->target(glfwGetWin32Window(window), width, height);
// ...
// terminate engine and window
tvg::Initializer::term(tvg::CanvasEngine::Wg);
`
Still this feature is under the beta
