pygame.display.update()

Should we add a few lines in here to show how to use the PIL Image.save() function to save the pictures to a file?

adding a comment or new example would be fine - a PR would be welcome!

@ramgarden Would a separate example be OK? That example continuously reads and updates a pygame display. Adding a PIL save in the loop would create lots of files, or just keep orverwriting the existing one. It would also slow down the pygame display update.

This is resolved.
