Hi

If I remember right Illumen from #pygame said some days ago he added 
this feature to the pygame CVS ( http://www.pygame.org/wiki/cvs ). I did 
not look into the CVS but it should be there.

I forggot a imortant line in the last (pseudo) code fragment:


#----------------------------------------------------
if sprite.rect.colliderect(oldrect): #<------------ important
   unionrect = oldrect.union(sprite.rect)
   if unionrect.width*unionrect.height< 2*sprite.area: # assumes that 
oldrect and sprite.rect has same area,
   
                                                                      
  # if not its only for one frame
   
                                                                       
 # perhaps I should also save the oldrect area to do it right
      screenupdates.append( unionrect )
   else:
      screenupdates.append( spr.rect )
      screenupdates.append( oldrect )
else: # <------------------------------- and from here on
   screenupdates.append( spr.rect )
   screenupdates.append( oldrect )
 
#----------------------------------------------------
