1. The logic for finding the active pointer was incorrect. The code was
iterating over all pointer ids and taking the minimum, i.e. the pointer
that first went down. The problem was that the down time for pointers
that are not down was also considered (set to zero), thus sometimes we
would consider the first pointer that went down to be a pointer that
is not down at all. Now we are iterating only over the pointers that
are down.
2. The batched events while waiting to see if the user is exploring or
gesturing were added even if we were in touch exploration state at which
point we do not have to batch. As a result we ended up having lefovers
from a previous gesture when handling the delayed events and crash.
