using the Rect objects it is very easy to do a 'centered' blit. you 
create a rect object, use one of its handy assignment attributes, and 
then blit with that position. no need for special math os subsurfaces


def blit_centered(src, dst):
    r = src.get_rect()
    r.center = dst.get_rect().center
    return dst.blit(src, r)

you can use this function to blit any source image to any destination 
image and have the two centers shared.
