Using maketx to generate a tiled mip-mapped exr

$ git clone https://github.com/openexr/openexr-images.git
$ docker run --rm -v ${PWD}:/mnt/${PWD} ayoburgess/oiio maketx -v -u --oiio --checknan --filter lanczos3 /mnt/${PWD}/openexr-images/Chromaticities/Rec709.exr -o /mnt/${PWD}/openexr-images/Chromaticities/Rec709.tx
