NonSupport indicates unsupported options due to disabled features
or lack of system support. InvalidArgument indicates the case
such as incorrect parameter values.
The functions setting stroke's features always
returned a true. Returnig a boolen was a remnant
from a previous implementation. Since now they
never return false, they can be void functions.
The APIs description has been corrected.
New api sets/gets the trim of the stroke
along the defined path segment, allowing
control over which part of the stroke is
visible.
@issue: https://github.com/thorvg/thorvg/issues/2190
For angles close to multiples of pi/2, precision
based on FLT_EPSILON was insufficient. It either
led to the creation of an additional cubic segment
filled with erroneous values or NaNs, or it resulted
in the drawing of an angle for a sweep close to 0.
According to the SVG standard, drawing a rectangle
starts at (x+rx, y) point. Till now it was (x+w, y+ry).
The difference was visible only for dashed strokes.
According to the SVG standard, drawing a circle/ellipse
should start at the '3 o'clock' position and proceed
in a clock-wise direction. Until now, this point was
set at '12 o'clock'.
The differences in the outcome were visible for dashed
strokes.

adjusted the starting position of the rounded rectangle to 90 degrees
to ensure compatibility with the Lottie trim path effect.
This modification follows the earlier circle correction applied to the rectangle.
issue: https://github.com/thorvg/thorvg/issues/1933
the bug was introduced in 9bf8bb018d.
Migrated the circle commands to the rectangle, which is currently necessary.
Retained the previous circle commands for backward compatibility.
Adjusted the path's start point to 90 degrees
to align the origin consistently with other path commands.
No compatibility issue, this only could affect the trimpath effects.
The magic number kappa (0.552284), which is associated with the bezier curve,
has been introduced. This formula is supposed to be applied to the rounded corners
of the rectangle to ensure consistent drawing results.

Get rid of the polymorphism function table,
use the switch directly instead.
We profiled, both binary & performance is better than before.
Tested on a local machine (single thread):
- Lottie: 2ms improved
- Binary: -0.5kb
