Public Member Functions
void	LockCurrentResolution ()
	Lock the current screen viewport resolution. This method will cause the map renderer to use the same resolution for all zoom levels, until you call UnlockResolution again. Please note that this will cause severe performance problems when zooming out, and severe rendering artifacts when zooming in.
void	UnlockResolution ()
	Unlock the screen viewport resolution. See LockCurrentResolution().
bool	IsLockedResolution ()
	Returns true if the screen resolution is locked to a specific value.
	GeoContext (IViewport viewport, bool useTransitions=true)
void	BeginTracking (Point pt)
void	UpdateTracking (Point pt)
