Add missing return.
Whoops. Not sure how I missed that. Guess that's what happens when
you don't unit test...
Add test to Makefile
Nothing too exciting, just compares a checksum. The fact it depends on a file
I *know* is going to be modified makes it kind of stupid, but it works for

someone wants to test in some bash-free environ, they can check the sha1 by
hand. Sorry!
Forgot the newline again.
Better arg parsing format.
Add -h option
Add -x and -y options for width and height
Uncovered a bug with dealing with pictures too small, I'll fix it next patch
Stop small x/y from segfaulting
Makes it so that reading the file is done until there's no more room left in
the generated picture, if that's the limiting constraint.
Merge branch 'master' into read
