Feature: Dithering to reduce banding artifacts #1881

Description

@krisCatboy

Which component should be improved?

Rendering

Describe your feature suggestion in more detail

"dithering" is often employed during rendering to smooth out "banding" artifacts, which are especially apparent with gradients that can go from very dark to bright, such as fog or lighting.

strata should get an implementation of something like this.

below i have attached a comparison showing a similar setup in p2ce, godot 4, and godot 4 with its "debanding" feature enabled. the right column boosts the contrast to show the banding clearly, and how effective dithering is at eliminating it.
