commit 39086ebbe64239517f18000ae252f83f1dbaaf23
Author: leszek <leszek@koltunski.pl>
Date:   Mon Mar 6 22:29:53 2017 +0000

    New method of rendering.
    Advantage: now there's one (well, ATM two, but I hope soon really in one) place where we can have a look at all the Meshes that are being rendered to a OutputSurface.
    This should help with proper per-object POSTPROCESSING effects like Multiblur.
