Fine, I'll clean the code a bit and then commit the changes.

I was thinking about this, too, partly to help debug the code. I can
come up with the code to do this and a simple (drawn) crosshair image,
but I have never used povray (or any other raytracer) so I'd rather have
someone else create the final image.
You will never shake it off cause the AI sees the whole screen (just as
the player), the x coordinate is just adjusted so that the target is in
front of the missile. Therefore the missile does not turn around if the
target suddenly warps behind it.
Of course it would be possible to assign a viewing angle to the missile.
In that case the warping has to be taken into account to avoid shaking
the missile off by just leaving the screen on one side. This would
necessitate aiming the missile towards its target on creation time when
shot by ufo or bonus machine as well (which would look better too).
At the moment you can escape the missiles by leading them into an
obstruction or running away until the missile is out of fuel.

That's no problem. I'll use a named constant to set this value so it
will be easily adjustable.
