In the case of a transformation (denoted as T1)
appearing after the repeater, but at the same
level of nesting, the objects to which the repeater
is applied should not consider T1. However,
the transformation of the repeater itself should
take T1 into account.
Also, it is possible to have several consecutive
repeaters, and all of them should be taken into
account. Until now, the last one was overwriting
the previous one.
So far it hasn't been possible to specify
a matte layer - by default, it was the layer
above the calling layer. The 'tp' tag support
has been introduced, enabling referencing any
layer by its index.
In cases where the layer referencing the matte
was the first one, a segmentation fault was
observed. This issue has now been resolved.

Handled the case of different numbers
of points in consecutive frames. This
case can occur due to erroneous data
or as a consequence of changing the path
from closed to open and vice versa.

Rather than aiming for extremely high accuracy,
a compromise can achieve with better performance.
This modification helps prevent unnecessary image rotation.

[issues 1479: Fill Rule](#1479)
In this solution we dont need to find silhouette, that is not a cheep operation (decreasing performance in 2 times)
For winding, you can select separate operations for front and back faces (increment for front, decrement for back)
After rendering the fan, the value in the stencil buffer will be the winding number. You can fill the appropriate portion by rendering a screen-sized quad with stencil testing enabled and the stencil function set according to which winding rule you wish to use.
For even-odd, you don't need to distinguish front and back faces; you can just use INVERT as the operation.
The viewport function defines the rectangular area of the canvas
that will be used for drawing operations.
It is used to clip the rendering output to the boundaries of the rectangle.
Apps can use this function to set the drawing region within the canvas.
When the ThorVG canvas is partially inside the screen area such as during scrolling
it could help enhance rendering performance.
New Experimental API:
- Result Canvas::viewport(int32_t x, int32_t y, int32_t w, int32_t h) noexcept;

- Separate the rounded corner logic from the updateStar
since its logic has become too lengthy and complicated.
- Revise the path generation to eliminate duplicates.
Added support for skew transformation by
a specified angle around a specified axis.
Applied to layers and shapes, not to repeaters.

Implementation of the roundness property
for a polystar. Only the corners that were
not subject to rounding by the inner or
outer roundness parameters are affected.

When resetting back to animated property, system causes an UAF because frames have been freed.
Mark frames in nullptr at the case, so it doesn't use frame data after freed.
Issue: #2255
The display property, like any other node's style property,
should be part of a node style. This ensures its correct
copying and inheritance.
For the 'symbol' node, which is not rendered unless it is
used within a 'use' node, the display property can also be
applied. Because of that it cannot be utilized during scene
construction to determine whether the symbol is being defined
or used within a 'use' context.
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.
