Proposed patch

I made a mistake checking the performance of the solution, we can do it without the modff. This patch avoids using modff to avoid precision errors.

Not sure why in Qt solution they do not pay attention to the end angle in this situation, maybe it is a bug, and in case of skia they do not use anticlockwise property, which could cause issues with fill rules AFAIK.
