#version 450
// crt-royale-bloom-approx.slang #includes "bloom-functions.h", which checks
// whether PHOSPHOR_BLOOM_FAKE is defined to decide whether to use:
// a.) bloom_approx_size_x (default 320.0), or
// b.) bloom_approx_size_x_for_skip (default 400.0)
// from "user-cgp-constants.h." This is used to calculate a blur sigma (which
// incidentally is only used by some codepaths). These values often differ:
// a.) 400x300 is better for the fake-bloom shader.
// b.) 320x240 can be a better choice for the real bloom shader.
// The only purpose of this file is to tell bloom-functions.h which to assume.
