bin method
Replays commands through the binning core, yielding to the event
loop (and checking cancellation) every ~1024 commands so a worker's
cancel message can preempt a long walk - the same cooperative scheme
as the worker's record path.
Implementation
Future<void> bin(List<PdfRenderCommand> commands,
{PdfCancellationToken? cancellation}) =>
replayCommandsCancellable(commands, this, cancellation: cancellation);
