enable GL_EXT_fog_coord. Calculate fog factors and submit them instead of fog coords (it seems the chip cannot do fog factor computation when not using fragment depth as fog coord source). vtxfmt uses fallback for now (most code present but some magic would be needed if replaying vertices is necessary later on).
