NAME
fade_out - Gradually fades the palette to black. Allegro game
programming library.
SYNOPSIS
#include <allegro.h>
void fade_out(int speed);
DESCRIPTION
Fades gradually from the current palette to a black screen. The speed
is from 1 (the slowest) up to 64 (instantaneous).
Note that this function will block your game while the fade is in
effect, and it won't work right visually if you are not in an 8 bit
color depth resolution.
