#5919 reduced the load time for images that have consecutive tiles only differing in their offset. The test image in
test_timeout()was a TIFF file, but the change was made more generally to ImageFile.After python-pillow/docker-images#232, QEMU jobs in the docker-images repository are slower, and
test_timeout()is now timing out.This PR adds specific logic to TiffImagePlugin. Each tile has the same width and height, so if that width and height covers the image and there are no layers involved, then only the last offset is needed.
