Summary Fall out of simple image layer optimization if the image has EXIF rotation

We need to transform the image when painting it, so we need to fall out of the optimization. We could do some complicated things to keep the optimization in this case, but it's not a super critical case and the simple image layer optimization is relatively new. <rdar://problem/14071174>

Conveniently the layer is already the right size/shape, so we really just need to tell RenderLayerBacking to do the right thing.

Wouldn't a ref-test be nicer here?

(In reply to comment #5) > Wouldn't a ref-test be nicer here? Yes; I just borrowed the existing image-orientation test and made it composited, though.
