- Compute samples positions on CPU. - Use 3x3 Box blur instead of 2x2. - Implement bokeh parameters. With this commit, dof performance is almost negligeable. The quality is a bit lower than before but can be improve. Also now big Circle of confusion are supported (up to 200px). Cost is ~1.25ms on AMD Vega with a 2560p viewport than full HD and pretty shallow depth of field. Coc downsampling and dilation is not used anymore for now (commented).
