Implementation
Future<(bool, Point, Point)> clipLineAsync(Rect imgRect, Point pt1, Point pt2) async =>
cvRunAsync((callback) => cimgproc.ClipLine_Async(imgRect.ref, pt1.ref, pt2.ref, callback),
(completer, p) {
final success = p.cast<ffi.Bool>().value;
calloc.free(p);
completer.complete((success, pt1, pt2));
});
