Workbench: Depth Of Field: Improve noise and Large radius
- Add noise to remove undersampling artifact - Create 2 mipmaps to the scene color buffer in order to have bigger blurs - Replace blur2 with a 3x3 median filter that doesn't dilate the highlights - Use temporal accumulation to remove noise For some reason all of this exacerbate some bleeding issues happening on far foreground elements from near foreground elements. The actual problem was already happening before but was not really noticeable. It needs some more work to be fixed.
