dither (lygia/sample/dither)

sample a texture and dither using a 8x8 Bayer matrix

Dependencies:

Use:

<vec3> ditherBayer(<SAMPLER_TYPE> tex, <vec2> st, <vec2> resolution)

#ifndef FNC_SAMPLEDITHER
#define FNC_SAMPLEDITHER
vec4 sampleDither(SAMPLER_TYPE tex, const in vec2 st, const in vec2 resolution) {
    vec4 color = sampleNearest(tex, st, resolution);
    gamma2linear(color);
    color = SAMPLEDITHER_FNC(color, st * resolution);
    linear2gamma(color);
    return color;
