22771b5d8a loader/lottie: fix a broken masking feature. 
the inverse alpha should keep its own value.
previously, it's modified to alpha by a mistake.

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.

ce5ac1c114 loader/lottie: fix a crash issue caused by incorrect gradient alpha handling. 
This fix addresses the interpretation of gradient alpha values,
preventing a potential crash due to invalid memory access.

4127f4ce7a loader/lottie: revised the key-frame searching 
Replace the linear search algorithm with binary-search.

The performance enhancement may not yield significant benefits in normal cases.
However, it becomes crucial if the animation comprises an extensive number of frames...

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.

f31076a67e utils/str: Supplements functions. 
Added strDirname(), which returns the directory path name from the given string.
Added str2int(), which converts from the string to the integer.

These functions are used to supplement the existing string manipulation functions in the utils/str module.

4786ffc315 lottie_loader: fixing error with math consts 
The math.h was included before the _USE_MATH_DEFINES
was defined (in tvgMath.h) causing an error while
MinGw was used.
Since non of these header is needed directly, the header
is removed.
