/*
	Modifications (last one on top):
		20121014 - WVR: Added second Tracker Source for Arduino solution. The two will be mutually exclusive.
		20120929 - WVR: Disable button Filter-settings when StartTracker.
		20120918 - WVR: When AutoStart is TRUE, the program is not directly minimized any more.
						This now depends on the AutoMinimize time. Fixed the 'not showing' of the MIB.
						Also disable combo and buttons after 'Start'.
		20120917 - WVR: Added Mouse-buttons to ShortKeys.
		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.
