Simple and as suckless as possible Snake clone that I'm writing for a
GNU/Linux course at Ferraris school in Empoli.

I'm using SDL 2 for drawing and input handling, but the code is written
to make it very easy to port to other platforms/libraries. For instance,
I would like to use biscio to learn XCB.

At the moment the draw snake routines don't work. I need to fix them. I
suck at math. I guess I'll need more than one point coordinates to
correctly depict the snake and its turns on screen.

In Italian, "biscia" is a small serpent-like animal, not poisonous.
This game is simpler and smaller than Snake, hence the name. Biscio
would be the male version of "biscia", a word which has no male
conjugation in Italian. But biscio sounds funny.
