Title: imageByFilteringImage: Is influenced by device orientation

This was causing incorrect behavior for us, and it's probably not right in general. Basically if you have a single UIImage and you're trying to run in through a filter, the orientation of the output image should end up being the same as the orientation of the input image.

Before change, Orientation=UpsideDown, image orientation down:
