paintAt()

KisSpacingInformation KisDuplicateOp::paintAt ( const KisPaintInformation & info )

The implementation of painting of a dab and updating spacing. This does NOT need to update the timing information.

The saved layer might have been deleted by then, so check if it still belongs to a graph
