This commit creates a new built-in postprocessing shader that's designed to hold miscellaneous postprocessing effects, and starts it off with chromatic aberration. Possible future effects include vignette, film grain, and lens distortion. [Chromatic aberration] is a common postprocessing effect that simulates lenses that fail to focus all colors of light to a single point. It's often used for impact effects and/or horror games. This patch uses the technique from *Inside* ([Gjøl & Svendsen 2016]), which allows the developer to customize the particular color pattern to achieve different effects. Unity HDRP uses the same technique, while Unreal has a hard-wired fixed color pattern. A new example, `post_processing`, has been added, in order to demonstrate the technique. The existing `post_processing` shader has been renamed to `custom_post_processing`, for clarity.

To use it, add `ChromaticAberration` to your camera. |
