Refactor the GlCanvas::target() interface to allow
passing the drawing target ID from the user side.
Previously, it performed the drawing on the currently set FBO target.
Beta API change:
Result GlCanvas::target(uint32_t* buffer, uint32_t stride, uint32_t w, uint32_t h)
-> Result GlCanvas::target(int32_t id, uint32_t w, uint32_t h)
sw_engine: radial gradient
[issues 2014: radial gradient](#2014)
Radial gradient results in a corrupted image when the focal point is outside the circle on Apple Silicon.
This happens because some compilers use FMA to optimize the a = dr² - dx² - dy² calculation,
which cause loss of precision.
We rely on temporary variables to prevent FMA.
We could also use compiler specific float contraction control pragmas to avoid this if this doesn't work in the future
resolved a corner case where assets were being attached
multiple times during scene building. This issue was causing
a significant performence drop in image animation
in certain scenarios.
ThorVG has offered an option to clear the buffer since version 1.0.
This is essential when users utilize the canvas target buffer
with the main render target. They share the buffer
and need to draw contents onto the existing contents.
API:
Result Canvas::clear(bool free = true)
-> Result Canvas::clear(bool paints = true, bool buffer = true)
Tvg_Result tvg_canvas_clear(Tvg_Canvas* canvas, bool free);
-> Tvg_Result tvg_canvas_clear(Tvg_Canvas* canvas, bool paints, bool buffer);

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);

- The TVG binary format now consistently compresses the data.
- Removed redundant internal properties as part of this change.
Please note that this change will break compatibility with the TVG file format from version 1.0 onward.

This change introduces the CanvasEngine::All type to automatically
initialize the engines available on the current system.
These revisions improve the usability of these APIs.
Addtions:
- enum class CanvasEngine::All
Modifications:
- Result Initializer::init(CanvasEngine engine, uint32_t threads) ->
Result Initializer::init(uint32_t threads, CanvasEngine engine = tvg::CanvasEngine::All)
replace the frame count unit from the int32_t to float
since animations could smoothly interpolate key-frames.
This notificably improve the animation smoothness in Lottie
Beta API changes:
Result Animation::frame(uint32_t no) -> Result Animation::frame(float no)
uint32_t Animation::curFrame() const -> float Animation::curFrame() const
uint32_t Animation::totalFrame() const -> float Animation::totalFrame() const
