When I think about this again, I have no evidence or experience to confirm
that GIMP handles binary pixels. I suppose ImageMagick (imagemagick.org)
has the necessary convertor just in case.

It should also be possible to open the bitmap in a binary editor and replace
every 0 with, e.g. 0000000000000000 and every 1 with 1111111111111111. The
simplicity of this conversion makes it an interesting DIY problem.
