When I was testing the the pen support on Windows during initial implementation, I encountered some cases where injecting pen input would take a non-trivial amount of time per event and lead to a massive backlog of input events that caused input latency. Unfortunately, it's not always easy to reproduce (perhaps it depends on the window message processing latency of the focused application). We should probably have some batching to ensure we aren't sending pen events at a completely insane rate that the OS can't keep up with.

@cgutman Is it possible to make it an option? Users can choose whether to have batching or not.
