Added support for Text Based of Text Range Selector, by processing further properties:
2. Character Excluding Spaces
3. Words
4. Lines
see: https://github.com/thorvg/thorvg/issues/2178
Since the text node wasn't pushed onto the loader's stack,
closing the text node incorrectly caused an element to be
popped from the stack (if one was present).
This could result in elements that were supposed to have
that element as a parent being rendered incorrectly or not
being rendered at all.
Now, the text node is correctly pushed onto the stack.

If for any reason an invalid glyph is found in text,
it will now be skipped when rendering
(instead of increasing offset by last valid glyph advance).
Issue: #2687
According to the definition of trim path elements,
the begin and end values are specified as percentages
in the range of 0-100% (this is also confirmed by AE,
where it's not possible to exceed this range).
Added clamping to align with spec.
The range of saturation and brightness values is 0 ~ 100% and range of hue is 0 ~ 360.
If a value greater than 100% is loaded, it will be modified to be 100%.

To avoid editing the trim path values provided
by the user, the logic for their interpretation
was moved from the API to the renderer (7c87d8e).
This caused an issue in the lottie animations when
the trim path is applied more than once. Now fixed.

previously font size & italic style had been ignored
even if its attributes are changed.

Due to the lack of an analytical solution for Bezier
curves offsetting, a simple and computationally cheap
approximation has been implemented. The algorithm shifts
the segments connecting control points and determines
new points based on their intersections.
@issue: https://github.com/thorvg/thorvg/issues/2230
The occurrence of a 'carriage return' (13) or 'end of text' (3)
caused the skipping of the next character check, immediately
searching for it in the list of available characters.
If the next character was also 13 or 3, it led to incorrect
interpretation; however, if it was the last character in the
sequence, a crash occurred.
Spec out this incomplete experimental feature,
this is a still promising one, we will reintroduce
this officially after 1.0 release

In certain cases, the user might want to set mapped memory directly.
This update ensures that a null terminator is appended to the string data.

For rounded rectangles the roundness value should
be determined using to the formula:
r = min(r, max(size.x, size.y)/2)
rather than the previous method:
r = min(size.x/2, size.y/2, r)
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)
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
issue: https://github.com/thorvg/thorvg/issues/2608
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.
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.
LottieRenderPooler is designed to manages rendering
instances(paints) efficiently through a simple pooling
mechanism to resuse among the animations
This replaces the previous individusal paints implemenations
among solidfill, precomp vierport and pictures,
also fix a potential paints corruption problems.
