Revision 001fb991

Largely fix the non-postprocessed OIT. Still, one problem remains: back-facing surfaces seem to disappear (visible in 'Cubes')

     // Otherwise, render to a buffer and on each change of Postprocessing Bucket, apply the postprocessing
     // to a whole buffer (lastQueue.postprocess) and merge it (this.oitBuild).
