516e8bf042 loader/lottie: minimum support for 3D transform 
It lacks perspective projection information,
so it transforms 3D axes with orthogonal projection.

7c669f622f loader/lottie: enhanced the coverage of the rounded corner feature. 
Rounded corners should now be applied not only to rectangles
but also to path strokes. This enhancement changes the stroke join style
to round when a rounded corner is present.

Indeed, rounded corners ensure the accurate calculation of roundness based on the join style.
However, this patch has not yet been designed to handle it.

735c1cb9e4 sw_engine: fixed a antialiasing issue. 
Previously, a mechanism was introduced to skip antialiasing computations
when shapes are invisible due to their stroking. However, this mechanism
failed to account for the scale factor of the stroke; it only considered
the current stroke width as a threshold.

Consequently, when the stroke width is scaled up to a value smaller than
the threshold, the incorrect antialiasing approach is applied. This results
in the appearance of jagged edges.

The implemented fix rectifies this problem and ensures that the antialiasing
computation correctly takes into consideration both the visibility and the
scale factor of the stroke width.

21413b1872 sw_engine: optimizing the masking feature 
replaced 32-bit operations with 8-bit operations for masking buffers.

We might need a grasycale image support for applying 1-byte channel masking input(Picture).
Some of masking implementation are disabled by this reason.

Also, I don't expecct it's necessary for the thorvg now.

624b275628 sw_engine: improve the masking methods 
Corrected subtract/intersect masking behaviors that were inaccurately functioning
within chain-masking.

This also helps to enhance the masking performance by reducing the
