There's a maximum field length possible, and we should/could use that as padding. Say for 8 bits, the worst-case is something like: 1-2,4-5,7-8 right? The max is roughly len*3/2. I see a problem there: for something larger like 256 it would lead to quite some padding ... Well, we could just skip doing width for now - the ability to easily print bitmaps is very valuable in itself.
