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.
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);

We've changed the behavior of Canvas::clear(false).
The canvas::clear(false) now retains the paints, allowing the user to update the next frame
more easily without having to recompose the paint list.
Previously, clear(false) removed the paint list from the canvas,
requiring the user to re-push all of them in the next frame.
Now, we offer the Canvas::paints() API, allowing users to modify the paint list directly instead.
This change will break compatibility with previous versions of Canvas.
Therefore, this update is included in ThorVG 1.0.

WARNING:: You should add the boolean check kwarg to the run_command call.
It currently defaults to false,
but it will default to true in future releases of meson.
See also: https://github.com/mesonbuild/meson/issues/9300
Rule of thumb on Windows:
* for a DLL:
* if the library is built, set TVG_API to __declspec(dllexport)
* if the library is used, set TVG_API to __declspec(dllimport)
* for a static library, set TVG_API to nothing
To set TVG_API for a static library, TVG_STATIC is defined when the stataic library is built.
Otherwise, TVG_API is correctly set for a DLL.
Also sun and intel compilers are handled

The previous meson script was incomplete,
therefore this change requires it to be revised.
To enable static linking use the next meson option.

Basically, this Accessor is a utility to debug the Scene structure,
by traversing the scene-tree by users.
You can search specific nodes to read the property information,
figure out the structure of the scene tree and its size.
We actually don't recommend you to touch the property unless you really
know the each paint's position and role because it's not visible, difficult to
understand its anatomy.
Also, You must underatnd that modifying the nodes of the scene will be going
well with both the art-design structure and the prorgram logic.
In this first version, Accessor only supports for the Picture class.
@example:
auto picture = tvg::Picture::gen();
picture->load("test.svg");
//The callback function from lambda expression.
//This function will be called for every paint nodes of the tree.
auto f = [](const tvg::Paint* paint) -> bool
{
if (paint->identifier() == Shape::identifier()) {
//override properties?
uint8_t r, g, b, a;
paint->fillColor(&r, &g, &b, &a);
paint->fill(r / 2, g / 2, b / 2, a);
}
//You can return false, to stop traversing immediately.
return true;
};
auto accessor = tvg::Accessor::gen();
picture = accessor->access(move(picture), f);

Add RawLoader class that loads and display raw images,
and adds a Rasterizer for image data.
Image data can be loaded via picture.
Loaded image supports Composition, Transformation and Alpha blending.
New API
Result load(uint32_t* data, uint32_t width, uint32_t height, bool isCopy) noexcept;
We introduced separate opacity interface to adjust alpha value by paint.
This opacity will affect to whole paint image if paint is a group of paints.
Also, this opacity is to multipy with fill/stroke alpha values.
This means if the opacity is valid, the paint might deal with a composition step,
which is very expensive due to additional rendering step.
One tip is, if you want to toggle on/off for a certian paint,
you can set opacity to 255 or 0.
@API Additions:
Result Paint::opacity(uint8_t o) noexcept;
uint8_t Paint::opacity() const noexcept;
