Detailed Description

Hard-coded tables of polygon stipple patterns used for "screen door" transparency (old graphics hardware).

does this material have transparency? If so enable transparency via one of these methods: A) alpha blending with two-pass rendering and painter's algorithm B) alpha blending with two-pass rendering and alpha test C) screen-door transparency with polygon stipple trick Removed since we don't need to worry about changing transparency every triangle - it's done once per command list now (or thereabouts).
