If you've looked into TM1 decoder source you'd notice that
compression_type structure list them as {colourspace, width, height}
format. This allows coded to encode it in up to quarter resolution and
then scale black - real blocks are always 8x8 IIRC.

Since our decoder ignores scaling, it decodes only (real) half of image
and it doesn't help that we have only one 24-bit sample.
