And I'm 100% confident that they *could* have done it that way, 
but they didn't. ;-)

If you look at the screenshots, you can see that the diagonals 
always have the same width (4*4 = 16 pixel). In your demo the 
diagonals are 3*4+3 = 15 pixels wide. And there is *no* way to 
correct this, because 1 CPU cycle = 3 display pixels. So you 
can only change the colors every n*3 pixel. So most of the 
color writes have to happen hidden behind other currently 
displayed objects.

IMO the solutions is much more complex, using PF, players AND 
the background color to shine through (like Eckhard said). 

But I have no code to prove this (yet).

Have fun!
