# Ideally, the classes Pack, Place and Grid disappear, the

# everybody uses w.pack_whatever(...) instead of Pack.whatever(w,
# ...), with pack(), place() and grid() being short for
# pack_configure(), place_configure() and grid_columnconfigure(), and
# forget() being short for pack_forget().  As a practical matter, I'm
# afraid that there is too much code out there that may be using the
# Pack, Place or Grid class, so I leave them intact -- but only as
# backwards compatibility features.  Also note that those methods that
# take a master as argument (e.g. pack_propagate) have been moved to
# the Misc class (which now incorporates all methods common between
# toplevel and interior widgets).  Again, for compatibility, these are
# copied into the Pack, Place or Grid class.
