Raycasting is a technique of drawing a three dimensional world by "casting"
out a line for each column of the screen and tracing it each step of the way
until it hits a wall, then calculating the distance that it had to travel
until it hits the wall. Based on the distance, we can figure out the height
of the line we need to draw, then draw it. After that is done, we go on to
the next column of the screen and repeat until all 128 columns of the screen
have been drawn. It's not really that compilcated, but it's a killer to try
to explain it.
