This completes the pipeline make-over, as started in 2006. With this option, during rendering, each sample for every layer and pass is being saved on disk (looks like non-antialiased images). Then the composite and color correction happens, then a clip to 0-1 range, and only in end all samples get combined - using sampling filters such as gauss/mitch/catmul. This results in artefact-free antialiased images. Even Z-combine or ID masks now work perfect for it! This is an unfinished commit btw; Brecht will finish this for strands. Also Halo doesnt work yet. To activate FSA: press "Save Buffers" and the new button next to it. :)
