// General Design
//
// * Take any existing input & word wrap into lines[] preserving
// formatting characters.
// * When drawing, formatting characters are processed but not shown
// or processed directly in many cases. E.g., \n is processed but simply
// causes us to go to our "next line" visibly.
// * Empty/blank lines = \n

This seemed real, very real, though if you thought about it properly you couldn't imagine lewdies actually agreeing to having all this done to them in a film, and if these films were made by the good, or the State, you couldn't imagine them being allowed to take these films, without like interfering with what was going on.\nWhen it came to the sixth or seventh malchick, leering and smecking and then going into it, I began to feel really sick. But I could not shut my glazzies and even if I tried to move my glazballs about I still not get out of the line of fire of this picture."
