5) Fixed point math is used for the depth "z" buffer
6) We're not just using floats for everything because this is still supposed to be fast on platforms without SSE2
7) Fewer variables is usually better
+ 8) All variables that are used inside the rasterizer loop must exist irrespective of feature level at the language level,
+ because OpenMP needs to be able to declare them "private". The compiler will of course optimize out the unused ones.
