Rotation of images is only needed to view a portrait image on a landscape screen or vice-versa. The typical reason for physically rotating the screen is to view a portrait image. In this case, no rotation of the image is needed; it's only the text that needs rotation. I could rotate the image, superimpose the text, and then rotate back again, but that would be inefficient. Actually, now that I have experimented with this, rotation seems to be reasonably fast. I was expecting that copies via the CPU would be a lot slower than blits done by the graphics chip. So I'm not going to worry about this for the time being.
