096b834771 lottie: fix text stroke's 'of' property 
The text stroke's 'of' property determines whether
the stroke appears above (true) or below (false)
the fill.
Previously, it was incorrectly used to decide whether
the stroke would render.

requires ensuring that clipping is based on fill rather
than on stroke. Fixed now.

38a4465656 lottie: fix viewport clipping issue when resize 
After resizing an animation, the base clipper for the viewport of the root scene did not update accordingly. This caused the animation to always be clipped by its initial size.

Additionally, this issue introduced a regression in v1 when the `Result Picture::size(float w, float h)` function was called.

72482877e7 portability: fix file size check on Windows 
Resolved an issue where parsing failed due to mismatch
between file size obtained via `ftell` and the actual
bytes read by `fread`. This occurred because newline
translation (`\r\n` to `\n`) in text mode altered the byte
count, leading to incorrect assumptions about the data size.
