Are you saying the first event is delayed until it knows whether it is

I suspect I am misunderstanding this and an event is sent, but want to
make sure.
There's an svg diagram showing the state machine in the doc directory.
It shows when events are sent. Short answer: the press event is sent
very early, the release event may be delayed.
And to pre-empt the next comment: feel free to come up with a better
solution that doesn't have said "annoying latency" but still allows for
tap-and-drag. If you do, please let us know in (pseudo)code rather than
general comments.
I feel like delaying the release event may work ok. Clients that don't
want latency would react to the press event. And if clients knew that
releasing everything meant they were not going to get anything other
than basic press events next it might be helpful.
