FlipX a CCSpriteFrame

Hi.

I added a set of sprite frames in sharedSpriteFrameCache with the method addSpriteFramesWithFile.

There are frames on that image those a need to duplicate, but flipping in X coordinate.

I want to create a new sprite frame, equal to one that is already in the sharedSpriteFrameCache but flipped and add it to the set of sprite frames in sharedSpriteFrameCache.

How do I do that?

Thanks.
