/* This file contains the internal paint_path() and paint_paths() methods,

/* This file also contains the internal path_is_flushable() method, which
   is invoked after any path segment is added to the segment list, provided
   (0) the segment list has become greater than or equal to the
   `max_unfilled_path_length' Plotter parameter, (1) the path isn't to be
   filled.  In most Plotters, this operation simply returns true. */

/* This file also contains the internal maybe_prepaint_segments() method.
   It is called immediately after any segment is added to a path.  Some
   Plotters, at least under some circumstances, treat endpath() as a no-op,
   and plot the segments of a path in real time, instead.  They accomplish
   this by overloading this method. */
