Detailed Description

A transfer's share of its screen's pending count.

A transfer is pending from the host accepting it to its settle: its completion carries on the command list that started it, which the close protocol and save-and-close wait for. The count is taken once the host accepts, so a refused transfer never counts, and a host that settles before it returns leaves nothing taken. It is given back once, also when the transfer settles after its scope is gone, but not after the screen itself is gone, since the count went with it.
