pippy examples can adapt to screen dimensions

[skierpage]

All the pippy graphics examples I looked at hardcode

# XO screen is 1200x900
size = width, height = 1200, 900

but that makes the activity resolution-dependent. Bad for emulation, and on the XO if you rotate the screen, Bounce's word goes off the side, etc.

I read http://www.pygame.org/docs/ref/display.html and it seems pygame defaults to full-screen and can determine display size.

I've never written a line of Python before but this fixes the Bounce example to work rotated:

# Don't need to set a screen resolution (SDL 1.2.10 and above),
# we can determine it dynamically (pygame 1.8.0 and above).
if pygame.get_sdl_version() < (1, 2, 10) or pygame.version.vernum < (1, 8, 0) :
  exit('Warning, version of Pygame too old,exiting!')

screen = pygame.display.set_mode()

# Ask for display's width and height.
display = pygame.display.Info()
size = width, height = display.current_w, display.current_h

or maybe better request the screen's size and width instead of the display's, so last two lines become (untested):

size = width, height = screen.get_size()

This seems to work rotated also, and is simpler/cleaner:

# Display defaults to screen resolution (SDL 1.2.10 and above),
if pygame.get_sdl_version() < (1, 2, 10) :
  exit('Warning, version of SDL too old,exiting!')
screen = pygame.display.set_mode()
size = width, height = screen.get_width(), screen.get_height()
