/** CbmVisPoint
 *@author Evgeny Kryshen <e.kryshen@gsi.de>
 *@since 02.04.07
 *@version 1.0
 **
 ** Class for visualization of MC points with the electron spread
 ** projection in xy plane. The spread projection is drawn as rectangle
 ** around IN and OUT positions in xy plane with a given radius.
 ** Constructors from CbmStsPoint and CbmMuchPoint are implemented.
 ** Default electron spread radius in STS is 0.0005 cm, in MUCH - 0.03 cm
