Tested on Windows. Now fabulous-demo will run!

There, now the tests pass on Travis-CI too!

Thanks for submitting this. I'd rather not introduce upstream dependencies. It might be better if we implement something along the lines of termios in combination with inband probing like \e7\e[9979;9979H\e[6n\e8 → \e[𝑦;𝑥R

@jart Are you still supporting Python 2.7 and 3.2?

Starting with Python 3.3, the required function was added to the standard library, and thus does not require any upstream dependency...

I'm happy to bump up to Python 3.3 but I definitely want to keep supporting Python 2.7. Perhaps we could simply keep doing what we're doing for 2.7 and have the update apply only to Python 3.3+ users?
