[Python-checkins] CVS: python/dist/src/Lib/lib-tk Tkinter.py,1.137,1.138

[A.M. Kuchling]

Update of /cvsroot/python/python/dist/src/Lib/lib-tk
In directory slayer.i.sourceforge.net:/tmp/cvs-serv10064/Lib/lib-tk

Modified Files:
	Tkinter.py 
Log Message:
Patch from /F:
this patch adds a fast _flatten function to the _tkinter
module, and imports it from Tkinter.py (if available).

this speeds up canvas operations like create_line and
create_polygon.  for example, a create_line with 5000
vertices runs about 50 times faster with this patch in
place.
