Lok: support for batch API calls
Mouse and keyboard operations typically
come in batches, and often each results in
tile invalidations and/or layout modifications.
Processing each input event on its own, then processing
the resulting output event is very costly and unecessary
when we know there is more of the same.
The new API adds support for batching such related
input events by disabling the output events generated
by Core until the batch is done. The client can
then process the resulting events, which will
be compressed and deduplicated.
