Implemented instructions CLIP and FCAND.
Unfortunately, the microprogram does some fiddling with the MAC flags and I'm not quite sure which result it wants to test. I'm guessing it wants to test the result of the OPMSUB with FD set to 0, so I put some hack in there to force a write of the MAC flag bit the microprogram needs. 
The garbage polygons are clipped accordingly now, but there's too many polygons that are being clipped. It's probably related to the MAC flags fiddling, but I'm not sure yet. I'll try to improve the rendering further tomorrow. |
