Efficient Triangle Coverage Tests for Stochastic Rasterization

In our previous paper on stochastic rasterization [Laine et al. 2011], we stated that a 5D triangle coverage test consumes approximately 25 FMA (fused multiply-add) operations. This technical report details the operation of our coverage test. We also provide variants specialized for defocus-only and motion-only cases.
