The class is responsible for coordinating all of the input systems in WPF.
The controls the input staging area. The input staging area processes input into Windows Presentation Foundation (WPF) events.
Input is processed in WPF in the follow stages:
Pre-process stage. The input manager raises the PreProcessInput event.
Pre-notify stage. The input manager raises the PreNotifyInput event.
The WPF input event or events are raised.
Post-notify stage. The input manager raises the PostNotifyInput event.
Post-process stage. The input manager raises the PostProcessInput event.
