The current Paint::bounds(transform=true) returns the coordinates
of the paint in its local coordinates after transformation.
However, it did not convert the origin to the world coordinate.
This is problematic when the user wants to determine
the paint's position and size with the origin being the canvas.
Specifically, this matters that when the paint is belonged
to a certain scene.
Now, the bounds() method returns the coordinates
of the paint's bounding box with the corrected world space.
User can figure out the actual boundary within the painted result.
Remark that, this may break the functional behavior compatibility.
This utility method allows access to a specific paint instance
by its unique identifier.
Experimental API:
- const Paint* Picture::paint(uint32_t id)
- const Tvg_Paint* tvg_picture_get_paint(Tvg_Paint* paint, uint32_t id)
This function computes a unique identifier value based on the provided string.
You can use this to assign a unique ID to the Paint object.
Experimental APIs:
- uint32_t Accessorr::id(const char* name)
- uint32_t tvg_accessor_id(const char* name)
Lighten is applied, where multiple masks intersect,
the highest transparency value is used.
Darken is applied, where multiple masks intersect,
the lowest transparency value is used.
Experimental API:
- CompositeMethod::LightenMask
- CompositeMethod::DarkenMask

For a linear gradient defined by identical start and end
points, and for a radial gradient with a radius of 0,
the rendered shape should have the color of the last
specified color stop.
The documentation has been updated accordingly.
@Issue: https://github.com/thorvg/thorvg/issues/2582
The logic of interpretation of trimming start and
end values has been moved to the sw_engine,
so the values provided by the user are not modified.
No logical changes in the interpretation alg.
For pairs of trim's start/end values where the distance
between begin and end is >= 1, the entire stroke should
be drawn, but instead, nothing or only part is drawn. Fixed.
Stroke trim docs fixed.
Adds the ability to load some composite glyphs and prevents an error when a composite glyph is used.
Implementation based on ttf glyf table documentation: https://learn.microsoft.com/en-us/typography/opentype/spec/glyf
There are still some missing features like scaling, parent glyph point based positioning etc. I think this is a topic for future work. Howerever, it looks like implemented features are enough for utf-8 latin subset in major fonts.
issue: #2599
- revised the transformation building logic.
- rectified to properly search "this" composition layers.
- rectified the linear interpolation implementation.
- added "pingpong" looping attributes.
The restriction of the 'length' of a linear gradient
to values greater than FLT_EPSILON was causing rendering
issues in cases where it was a valid gradient with well
defined dx and dy values.

More precisely, culling the render objects by
determining if the group has no renderable objects.
Additionally, check opacity to quickly return
in the rendering process.
