wip: incorrect bmp header.

try running nosetests - i can't work out how to test barrel correct
effectively. it has something to do with saving jpeg - i'm not sure that
you can make a duplicate of a jpeg with PIL.

after moving to debian wheezy, pil seems to have problems with reading
in bmp ---> something to do with imagemagick version?
Merge branch 'barrel-test' of github.com:aaren/lab-waves into barrel-test
