Re: [pygame] Sprite group drawing with offset

[Brian Song <unlucky777@xxxxxxxxx>]

I'm reading this from my iPhone so I can't verify that this is my
working version, but I can tell that it's missing something important.
I basically changed the sprite.RenderUpdates.draw() to accept a second
and third argument "offsets [x,y]". By default they are set to 0,0
(this is whats missing... Should be def draw(self,screen, offset =
[0,0])) so there would be no argument/type error when older code uses
the draw method without passing the offsets. I felt by letting the
draw method accept an offset, it would be easier to shift a whole
sprite group at once while adding sprite rects to a rectlist.
