Dashed curves require greater precision in calculating
their lengths and while splitting Bezier curves.
Otherwise, it results in visual discrepancies compared
to the expected outcomes.
Approximate functions 'bezLengthApprox' and 'bezAtApprox'
used for calculations in the lottie loader.

In the case of non-uniform scaling for
thick strokes, artifacts were visible.
The calculations took into account the angle
resulting from the already transformed points,
whereas the untransformed points should have
been considered - the transformation is taken
into account in the next step.

enhance decoding efficiency by determining the desired canvas format
during image loading. This allows loaders to preemptively decode
the image in the specified format, to not convert the format again.
Attempt to load a given file/data using candidate formats
when the desired loader fails. This approach will enhance
the compatibility with various file formats in unexpected scenarios.
Previously, we had removed this feature, but have since
recognized its necessity due to the impact on file data
in specific corner cases.
* add new render task to do stencil and cover rendering which is a
fallback rendering method to handle cases that trianglation tessellation
failed
* add a new tessellator to generate stencil and cover vertex mesh
Version 0.58 find missing libraries and causes an error.
(ex: libwebp 1.0).
There is no need to fix the current version, so always use the latest version.
Allow direct updates to the paint object without prior validation.
The verification process is deemed inefficient;
users are expected to ensure the paint is updated using a canvas
that contains it.
This might break the backward compatibility.
Adjusted the sampling position basis by -0.5 pixel
to enhance edge line interpolation quality.
This change addresses an issue with the image up-scaling process,
resulting in clearer and more accurate visuals.

Previously, the logic was set to halt rendering when any part of the paints,
particularly bitmap-based images, failed to render.
This update modifies the behavior to continue drawing the scene,
allowing for the successful rendering of other elements.

* merge vertices that are close enough before tessellation
* append return branch in tessellation to prevent dead loop caused by floating point precision
TVG picture binaries were maintained for compatibility checks.
These are generally not used by ThorVG developers.
Migrated those binaries to another repository to streamline
the ThorVG main repository.
dispose of the resources at the end of the paint deletion.
This will help retain the resources of the retained paints
and reuse them after reconstructing the next scene.
