Post #1681500

@floe Yep, based on my previous work (https://bitbang.social/@montyontherun/112938143172176814), but now improved and following as much as possible the GL ES 1.0 CL specification. Currently, the only other software implementation I'm aware of is the Mesa3D, but theirs convert from fixed-point to float internally. (Let me be clear that I have the uttermost respect and admiration for their work - and I help there from time to time) edit: spelling
