RgTools v1.0 (20200427)

RemoveGrain mode 26-28, (C, up to SSE4.1)
As said by the original author:
Mode 26 SmartRGC: 26 = medianblur. Based off mode 17, but preserves corners, but not thin lines.
Mode 27 SmartRGCL: 27 = medianblur. Same as mode 26 but preserves thin lines.
Mode 28 SmartRGCL2
pinterf: I swear that by seeing the code mode 28 is different from mode 27 but I cannot find a clip where 27 and 28 gave different results :)
Repair mode 26-28 (25 is nonexisting, only exists in RemoveGrain)
add "opt" debug parameter to Repair. 0:auto, 1:c 2:SSE2 3:SSE4.1 4:AVX2 (latter is not used here atm)

RgTools v0.99 (20200426)

RemoveGrain mode 25 ("nondestructivesharpen") finally reverse engineered
and ported from the original RemoveGrain package. (no-no, Repair has still 24 modes)
Plus: 10-32 bits, Plus: sse4.1, avx2
RemoveGrain: More correct 32 bit float in mode 6,7,8,9,15,16,23,24
(proper clamping, chroma part specially treated)
General: make C reference more similar to actual SIMD code
fix: width<32 (or 16) with horizontal subsampling would use AVX2 (SSE2) on chroma
(noticed: RemoveGrain: mode 11 and 12 SSE is simply avaraging
instead of really do 1/4 1/2 1/4 kernel blur like C (todo).
This is written in docs but even very old RemoveGrainSSE2 acts like this)
Avisynth+ V8 header, frame property copy support
opt debug parameter to RemoveGrain. 0:auto, 1:c 2:SSE2 3:SSE4.1 4:AVX2

RgTools v0.98 (20190814)

Include "TemporalRepair" filter from old RemoveGrainT package (rewritten C and SIMD intrinsics from pure inline asm)
Add Y8, YV16, YV24 besides YV12, drop YUY2 support.
Add 10-32 bit support for Y, YUV and planar RGB formats
Add int "opt" parameter (mainly for debug: 0=C 1=SSE2 2=SSE4.1) for testing specific code paths
Codes for different processor targets (SSSE3 and SSE4.1) are now separated and are compiled using function attributes (clang, gcc).
Other source changes for errorless gcc and clang build
LLVM support, see howto in RgTools.txt
Note: use at least LLVM 9.0 build 21 June 2019 due to a clang compiler bug (_mm_avg_epu8 related, fixed on April 14 2019) older versions are up-to 1/3 slower than the Microsoft build.
See latest snapshot builds at https://llvm.org/builds/
GCC 8.3 support, CMakeFiles.txt, see howto in RgTools.txt
RemoveGrain/Repair different code paths for SSE2/SSE4.1/AVX2 instead of SSE2/SSE3/AVX2.
Add documentation (from old docs, new part: gcc/clang howto)
todo: Overview 32 bit float parts for some RemoveGrain modes (6, 7, 8, 9, 15, 16, 23, 24)

RgTools v0.97 (20180702)

Remove some inherited clipping to 0..1 range for 32bit float.
In general we do not clamp in 32 bit float colorspaces, especially that U/V range is -0.5..+0.5 from Avisynth+ r2728

RgTools 0.96 (20170609)

RemoveGrain: AVX2. Available when Avisynth+ reports AVX2 usability
Can be disabled with new parameter: optAvx2=false
Clense, ForwardClense, BackwardClense: ignore planar colorspace checking when planar=true. Like in RemoveGrain and Repair.
Fix: Mode 11 and 13 for 32 bit float colorspaces (which worked like mode 10 and 12)

RgTools 0.95 (20170314)

Fix: RemoveGrain Mode 20: overflow at 14 and 16 bit depths in SSE4 (stripes)
"Repair": error on unaligned frames (unaligned crop) instead of access violation error

RgTools 0.94

Clense: new parameter (from v0.9): bool reduceflicker (default false)
Clense: dummy compatibility parameters: bool planar, int cache
Autoregister filter MT modes as NICE_FILTER for Avisynth+
(except for Clense: when reduceflicker is true, MULTI_INSTANCE MT mode is reported)
Alignment check in Repair and RemoveGrain (anti-unaligned crop measures)

RgTools 0.93
