0832a188fe animation/lottie: updated the frame count unit. 
replace the frame count unit from the int32_t to float
since animations could smoothly interpolate key-frames.

This notificably improve the animation smoothness in Lottie

Beta API changes:
Result Animation::frame(uint32_t no) -> Result Animation::frame(float no)
uint32_t Animation::curFrame() const -> float Animation::curFrame() const
uint32_t Animation::totalFrame() const -> float Animation::totalFrame() const

8af77ba5b1 lottie: Fixed trimpath to support simultaneous trimpath 
The previous version omitted support for simultaneous trimpath,
but it is now working as intended.

244e984df8 lottie/builder: Fix overlapped stroking outlines. 
Previously, the builder accumulated the outlines and fills
in one paint to reduce the rendering context.

However, this approach won't work for Lottie
if the resource contains multiple strokes with branched groups.

We should apply the optimization
only when the specified condition is satisfied.

1819fed033 renderer/paint: fixed a mismatched reference count. 
This correction ensures a consistent use of 'ref' and 'unref' for paints to release memory properly.
The memory leak occurred when a picture was not pushed to a valid canvas.

This issue was reported by the unit-test memory sanitizer.

5b8c66f5c8 lottie/builder: fix an invalid matting result. 
Previously, it ignored the matte when it was out of frames for the sake of optimization.
However, this led to an incorrect matting result.

It should make the scene invisible when the matting is invisible.

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.
