On: Clip control on the Apple GPU

[fabiensanglard]

I wrote about this a few years ago (https://fabiensanglard.net/polygon_codec/index.php).

It was a pain to lean indeed and the best resources were quite old:

- "CLIPPING USING HOMOGENEOUS COORDINATES" by James F. Blinn and Martin E. Newell

- A Trip Down the Graphics Pipeline by Jim Blinn (yes the same Blinn that co-authored the paper above).
