Been playing around a bit with samply to fix some performance issues in Minart (especially polygon rasterization and convolutions).
Ended up making a bunch of things quite faster, so now my old 3D Stanford Bunny demo went from ~12 FPS to 20 FPS on my machine.
But, since I was able to also make convolutions faster, I can add two hackish depth of field passes while keeping the old performance numbers.
