So the current choice is between 2 options:

1. Doing it with the PF, as shown in the quick hack.


- No kernel cycles required


- It'll probably be assymetric. The left part is eaten 
up by the HMOVE lines and when reducing the size, the 
stars come out on the far right edge.

- It's eating a few pixels more than required.

- The color of the cockpit, crosshair, stars is all the 

- I need to change the priority register. The stars are 
_always_ above the sprites then.

2. Doing an ANDing logic inside the kernel


- No cockpit drawn (Hey, to me this'd be a "pro" :-))
- None of the Cons of the PF solution


- Kernel cycles required (I don't know wether it's 
doable at all...)

- The starfield is displayed on the whole screen, but 
the sprites would start disappearing earlier on the 
borders. Might look strange.
