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

Adjusting the effect
The look of the CRT can be tuned with several settings:
- Line width and Line contrast control the visible scanlines. Enable Show vertical lines to draw the lines vertically instead of horizontally.
- Curvature bends the image outwards to imitate the bulge of an old screen (
0keeps it flat). - Noise and Noise size add static grain. Noise Frequency sets how many times per second the noise is refreshed (
0freezes it). - Vignetting, Vignetting alpha and Vignetting blur darken the corners of the screen.
- Interlaced Lines Speed animates the scanlines to make them scroll over time.
