great thought - just tried it

Interesting notes:
compiled on Mojave - black screen
compiled on high sierra - work on both!
Now. the interesting stuff is that all the 2d is also 3d (don't ask). and I worked out how to get that operational.
I'm going to try and reverse engineer Marks core code and see if I can find a different approach - can I'm not expecting him to come up with anything - anytime soon...
I have a feeling it's probably something to do with the way he mangles the screens/canvas and shaders. TBH if I could get to a stripped down version then I would be happier
