CRT effect
Applies a CRT effect, simulating an old cathode-ray tube television.

The effect combines several classic CRT artifacts that you can dial in independently: scanlines (Line width and Line contrast), screen Curvature, static Noise, and a darkened Vignetting around the edges. Set Interlaced Lines Speed to make the scanlines scroll, and Noise Frequency to control how often the static is refreshed (0 keeps a fixed noise pattern). Enable Show vertical lines to add vertical lines on top of the horizontal ones.
