Subject: [PATCH] Mirror actions now cache the horizontal flipped Surfaces,
 rather than flipping them during blitting. It wastes more memory, but the
 problem is that SDL fontend got considered slower, especially when a vertical
 flipping was done at the same time (ie. Bad Guy falling facing right).
