//Initial port to ReShade: SLSNe https://gist.github.com/SLSNe/bbaf2d77db0b2a2a0755df581b3cf00c
//Optimizations by Marty McFly:
// vectorized math, even with scalar gcn hardware this should work
// out the same, order of operations has not changed
// For some reason, it went from 64 to 48 instructions, a lot of MOV gone
// Also modified the way the final window is calculated
//
// reordered min() and max() operations, from 11 down to 9 registers
//
// restructured final weighting, 49 -> 48 instructions
//
// delayed RCP to replace SQRT with RSQRT
//
// removed the saturate() from the control var as it is clamped
// by UI manager already, 48 -> 47 instructions
//
// replaced tex2D with tex2Doffset intrinsic (address offset by immediate integer)
// 47 -> 43 instructions
// 9 -> 8 registers
//Further modified by OopyDoopy and Lord of Lunacy:
// Changed wording in the UI for the existing variable and added a new variable and relevant code to adjust sharpening strength.
//Fix by Lord of Lunacy:
// Made the shader use a linear colorspace rather than sRGB, as recommended by the original AMD documentation from FidelityFX.
//Modified by CeeJay.dk:
// Included a label and tooltip description. I followed AMDs official naming guidelines for FidelityFX.
//
// Used gather trick to reduce the number of texture operations by one (9 -> 8). It's now 42 -> 51 instructions but still faster
// because of the texture operation that was optimized away.
//Fix by CeeJay.dk
// Fixed precision issues with the gather at super high resolutions
// Also tried to refactor the samples so more work can be done while they are being sampled, but it's not so easy and the gains
// I'm seeing are so small they might be statistical noise. So it MIGHT be faster - no promises.
//Fix by BC46
// Removed the "0.5 * pixel" expressions in the DX10 or higher check.
// With the use of dgVoodoo at least, the previous code caused the entire image to be blurry and slightly mispositioned.

/*
Magic Bloom by luluco250
Attempts to simulate a natural-looking bloom.
Features:
--Wide bloom blurring, derived from the gaussian function
defined here: https://en.wikipedia.org/wiki/Gaussian_blur#Mathematics
--Eye adaptation, decreases or increases the brightness
of bloom according to the overall image luminance.
--Lens dirt, as standard I suppose. Really not much here.
It uses an image named "MagicBloom_Dirt.png" so make
sure you have one in your textures directory.
--Unwanted features can be disabled through
preprocessor definitions, saving performance.
Preprocessor definitions:
--MAGICBLOOM_ADAPT_RESOLUTION:
Determines the width/height of the texture used for adaptation.
It is recommended to use 256, but you can use as far as 1024 without issues.
Too low resolutions will make adaptation seem "unstable".
Must be a power of two value: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 etc.
--MAGICBLOOM_BLUR_PRECALCULATED:
If set to 0 the gaussian blur will be calculated inside the shader.
Otherwise, it uses a pre-calculated kernel (array).
--MAGICBLOOM_NODIRT:
If set to 1 all lens dirt related features are disabled.
Beneficial for performance if you don't wish to use lens dirt.
--MAGICBLOOM_NOADAPT:
If set to 1 all adaptation related features are disabled.
Beneficial for performance if you don't wish to use adaptation.
