[pygame] sprite engine

[DR0ID <dr0id@xxxxxxxxxx>]

Hi

yes I know well, that we have dirty rects already and I use them in my 
sprite engine :-) .

In many games and applications only a few sprites change in a frame. The 
pygame.sprite module does not take account to that and clears and 
redraws all sprites, regadles if they need a update. Ok, one could do 
this by hand. So I decided to write a sprite module to have it simple 
like with the old pygame.sprite but that the dirty update should happen 
automatically. Because of that my sprite engine is only faster if not 
all sprites are dirty ( in fact, it is a little bit slower, 5 fps by 500 
sprites of 32x32pixels). I want to write it in a matter that one should 
not have to change many things so one still can use the 
pygame.sprite.group for sprite handling (except clear() and draw() ). My 
sprite engine also supports layers (or z order) of sprites which had to 
be done by groups otherwise.

So if you write a game or application in there all is moving then the 
old pygame.sprite is better joice or perhaps event using flip(). But, as 
I said, many games do not need to repaint all sprite each frame and then 
my sprite engine is faster.

Sorry for my english and I hope you understand what I try to say.
