I noticed you had image export on your TODO list. Last night, I managed to hack out that feature! I did some non-trivial changes, so I thought I'd make an issue first before making a PR.

The biggest change in design that I made was creating a struct in C to store screen data: each character "cell" stores the ascii character, and the foreground/background color pair. When a project gets saved, it dumps the contents of this data to a text file.

The data file written to disk can then be parsed by a small C utility I wrote which generates a PPM file, which can then be converted to a PNG file via imagemagick. The program uses the color lookup table adapted from the gist you linked in your README, and a bitmap font which I converted to a C header include file via image magick, some light vim-ing, and xxd.

Not currently at the computer with the code on it, but I'll post some examples when I get the chance.

If this looks interesting to you, I can make a PR with the changes I made.
