Auto invert preview colors based on the screen color Basically, when the background color of the screen at certain points is dark, the preview at that spot is white, and when it is bright, the preview is white at that spot. This helps to keep the previews always distinguishable, regardless of the background color. 2021-05-17 02:24:49 +03:00			`shader_type canvas_item;`

Optimize AutoInvertColors shader Not sure if that single if statement counts as branching code, but it's generally a good idea to avoid if statements in shader code, so I used step instead. 2021-05-22 16:08:11 +03:00			`vec3 inverted = vec3(1.0) - COLOR.rgb;`
