2cada9c446 loader/lottie: code refactoring.
migrate transform from the group to the layer.
transformation is not necessary in group but layer.

This helps to reduce the unnecessary assigning of the transformation
in group instances.

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.

86aabb4df0 loader lottie: image optimization
In every frame, the image undergoes a Colorspace conversion attempt.

This approach aims to bypass the step by retaining the pre-converted image data.

I acknowledge that this might not be the best approach,
but it is proving to be quite effective at the moment.

df43f91644 loader/lottie: optimize the header task.
To achieve full threading efficiency,
the header should return the necessary properties:
view size, framerate, and duration.

This commit adds duration parsing.

Also don't do the header task in case of single thread
because there wouldn't be parallel effects.

- add an execeptional hanlding at parsing the assets.
