Opening or placing an image whose orientation turns it a quarter (EXIF or TIFF Orientation 5 to 8) stored the pixels turned but kept the resolution as stored, so a photo at 300 x 150 ppi came in at the wrong width and height. XResolution counts pixels in the ImageWidth direction of the stored image (TIFF 6.0, https://www.itu.int/itudoc/itu-t/com16/tiff-fx/docs/tiff6.pdf; EXIF uses the same tag, CIPA DC-008-2012, https://www.cipa.jp/std/documents/e/DC-008-2012_E.pdf), so a quarter turn now swaps the axes, in the size Open and Place use and in the stored image, with jxlread::oriented_resolution as JPEG XL does. Three kinds of TIFF did not follow their Orientation tag: - grayscale TIFFs with extra samples and 1-bit CCITT Group 3 TIFFs were not turned; - a CMYK TIFF with its inks together was turned but stored as RGB, losing its inks, and one with a plane per ink did not open ("Planar TIFF with CMYK color type is not supported"). They now turn as the other images do, and a CMYK TIFF keeps its inks, 8 bits each, written again with the turned resolution.
