// B = 1.0, C = 0.0 => Cubic B-Spline filter.
// B = 0.0, C = 0.5 => Catmull-Rom Spline filter. This is the default used in this shader.
// B = C = 1.0/3.0 => Mitchell-Netravali cubic filter.

/*
A collection of CRT mask effects that work with LCD subpixel structures for
small details
author: hunterk
license: public domain
How to use it:
Multiply your image by the vec3 output:
FragColor.rgb *= mask_weights(gl_FragCoord.xy, 1.0, 1);
The function needs to be tiled across the screen using the physical pixels, e.g.
gl_FragCoord (the "vec2 coord" input). In the case of slang shaders, we use
(vTexCoord.st * OutputSize.xy).
The "mask_intensity" (float value between 0.0 and 1.0) is how strong the mask
effect should be. Full-strength red, green and blue subpixels on a white pixel
are the ideal, and are achieved with an intensity of 1.0, though this darkens
the image significantly and may not always be desirable.
The "phosphor_layout" (int value between 0 and 19) determines which phophor
layout to apply. 0 is no mask/passthru.
Many of these mask arrays are adapted from cgwg's crt-geom-deluxe LUTs, and
those have their filenames included for easy identification

How to use it:
Multiply your image by the vec3 output:
FragColor.rgb *= mask_weights(gl_FragCoord.xy, 1.0, 1);
The function needs to be tiled across the screen using the physical pixels, e.g.
gl_FragCoord (the "vec2 coord" input). In the case of slang shaders, we use
(vTexCoord.st * OutputSize.xy).
The "mask_intensity" (float value between 0.0 and 1.0) is how strong the mask
effect should be. Full-strength red, green and blue subpixels on a white pixel
are the ideal, and are achieved with an intensity of 1.0, though this darkens
the image significantly and may not always be desirable.
The "phosphor_layout" (int value between 0 and 19) determines which phophor
layout to apply. 0 is no mask/passthru.
Many of these mask arrays are adapted from cgwg's crt-geom-deluxe LUTs, and
those have their filenames included for easy identification
