Freeing the TWAIN Session

When the TWAIN session handle is no longer needed, free the handle by calling L_TwainEndSession. At this point the TWAIN session handle becomes invalid. Before acquiring more images from a TWAIN source, establish a new TWAIN session handle by calling L_TwainInitSession or L_TwainInitSession2.
