A filter is any code that listens to PreProcessInput or PostProcessInput. Filters can modify the input staging area.

A monitor is any code that listens to PreNotifyInput or PostNotifyInput. Monitors cannot modify the input staging area.

The specified input is processed by all the filters and monitors and is finally dispatched to the appropriate element as an input event.
