some work on extreme/degenerate shit in GPU
...
* clip against Z then Y then X. apparently, fixes #310 . I had also observed hints that the hardware does it this way.
* truncate W to 24 bits before viewport transform.
* mark any polygons that have a W=0 at that point as degenerate. do not render.

3D: keep the rasterizer from accidentally going out of bounds when given very flat X-major edge slopes.
...
this, by a fucking shitshow of butterfly effect, ends up fixing #234 . technically, the rasterizer was going out of bounds, which, under certain circumstances, caused interpolation to shit itself and generate Z values that were out of range (but still ended up in the zbuffer). sometimes those values ended up negative, which caused these glitches when polygons had to be drawn over those.
about fucking time.

separate polygonID attributes for opaque and translucent pixels.
