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.
