Document how raised touches should be reported

It wasn't immediately clear before whether a raised touch should be
reported one last time with tracking_id = -1 in its FingerState, or just
dropped from the fingers array altogether. It turns out to be the latter
[0], so add some comments to make that clear.

Also move the information from a comment that had somehow been separated
from the FingerState struct, while we're at it.
