docs: Performs a fast blit from the source surface to the destination surface.
          This assumes that the source and destination rectangles are
          the same size.  If either src_rect or dst_rect are None, the entire
          surface is copied.  The final blit rectangles are saved
          in src_rect and dst_rect after all clipping is performed.
  
          Args:
              src_rect (Rect): Source rect.
              dst_surf (Surface): Destination surface.
              dst_rect (Rect): Destination rect.
  
          Raises:
              SDLError: If the blit fails.
