- NSBitmapImageRep -TIFFRepresentationOfImageRepsInArray:, -TIFFRepresentationOfImageRepsInArray:usingCompression:factor - NSImage -TIFFRepresentation, -TIFFRepresentationUsingCompression:factor: - renamed NSTIFFReader to O2Decoder_TIFF - renamed O2ColorSpaceType constants to kO2ColorSpaceModel ones - initial CG/O2ImageDestination implementation supporting simple TIFF encoding via O2Encoder_TIFF - O2DataProvider, O2DataConsumer work - Some CF related cleanup in O2/CG
