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.

d683d2e70d sw_engine: Do not handle exceptions for zero line length. 
While it may represent a dot with a stroke width,
ignoring its length is not a good idea.
