This shader tries to reproduce a CRT-like output without replicating a RGB patterns.
It has the following features:
- allows fractional scaling
- uses texture AA shader and subpixel scaling for evenly placed sharp pixels
- has a horizontal blur function which mimics bad signal quality of some systems (megadrive, psx)
- has a vertical blur function which mimics n64 vertical software blur
- adds some noise to mimic restless CRT colors
- has a curvator function
- looks good with resolutions <= 1080p
- has modest system requirements
- adds a slotmask to the output.

Features:
- uniform-nearest shader with parameterizable horizontal and vertical blur
- can be used to mimic horizontal composite effects and vertical software blur
- has a parameterizable colour bleeding option

Features:
- produces nearest neighbor look with fractional scales.
- uses texture AA shader code.
- uses hotizontal subpixel scaling.
- due to different pixel sizes, moving sprites change dimension if nearest neighbor is used with fractional scaling. This looks unsteady. This shader uniforms pixel dimensions. Output looks much quieter.

* Update crt-consumer.slang
Removed NTSC as it conflicts with saturation/hue, and can be used as a separate pass anyway. Fixed some mistakes. Massive speed-up from 120 fps to 450 fps on Intel HD630.
* Update crt-gdv-mini-ultra.slang
Removed NTSC, some corrections too.
* Update zfast_crt_composite.slang
* Update fake-crt-geom.slang
* Add files via upload
* add night_mode
* Update lanczos16.slang
fix minor artifacts
* Brightness fix scanline.slang
Permanent Brightness fix. No need to adjust "SCANLINE_BASE_BRIGHTNESS.
* fix scanlines misalignment
* Add gizmo-crt shader
