.PeepEvents(events, action, mask) ⇒ Object

Behavior varies depending on action.

PEEKEVENT or GETEVENT:

events is the max number of events to retrieve.
Returns an array of Events, or nil if there was an error.
GETEVENT removes them from the queue, PEEKEVENT leaves them.

ADDEVENT:

events is an array of Events (or specific event instances)
to append to the queue.
Returns the number of events added, or -1 if there was an error.
