/*
	Modifications (last one on top):
		20120717 - WVR: FunctionConfig is now used for the Curves, instead of BezierConfig.
		20120427 - WVR: The Protocol-code was already in separate DLLs, but the ListBox was still filled ´statically´. Now, a Dir() of the
						EXE-folder is done, to locate Protocol-DLLs. The Icons were also moved to the DLLs
		20120317 - WVR: The Filter and Tracker-code was moved to separate DLLs. The calling-method
						was changed accordingly. The save() and LoadSettings() functions were adapted.
						The face-tracker member-functions NotifyZeroed and refreshVideo were added, as 
						requested by Stanislaw.
		20110813 - WVR: Changed the presentation of the raw inputs: now a decimal digit will even show when '0'.
		20110404 - WVR: Migrated the FlightGear protocol to a separate DLL. The rest must follow...
		20110401 - WVR: The about-dialog was shown 'misplaced'. It was corrected.
		20110328 - WVR: Added the display for output-pose.
		20110207 - WVR: RadioButtons for 'Stop engine' added. It is now possible to choose Stop or Keep tracking.
		20110109 - WVR: Added minimizeTaskBar option added. It is now possible to choose minimized or tray.
