MvTools2 + Depan + DepanEstimate
2.7.24 (20171205)
Fix: MFlowBlur: possible access violation crash when nPel>1
New: MScaleVect parameter 'bits'. e.g. Analyze 8 bit clips, use their vectors for 16 bits
Move project to VS2017
2.7.23 (20171012)
Fix: MScaleVect wrong rounding of scaled motion vectors with negative components. e.g. proper scaling (-1;-2) to (-2;-4) instead of (-1,-3)
2.7.22 (20170830)
Misc: Stop using version suffix .22
Fix: [DCT 8x8@8bit] garbage on x64: internal assembly code did not save xmm6/xmm7
Fix: [DCT 8x8@8bit] safe multithreading for integer DCT (8x8 block size, 8 bit video): assembly had a single working buffer.
Fix: [MDegrain] did not release input motion vector clips in destructor, possible hang at script closing. Bug since 2.7.1.22 (introducing MDegrain4/5)
Mod: fftw conversion constant of sqrt(2)/2 is more accurate (was:0.707), 16 bit formats may benefit (by feisty2)
Fix: SSE4 assembly instructions in x64, broke on non-SSE4 processors
2.7.21.22 (20170629)
Fix: [MDegrainN] fix chroma plane processing, regression since 2.7.1.22
2.7.20.22 (20170526) - hotfix
Fix: [MMask] greyscale input resulted in AV when filter exiting
2.7.19.22 (20170525)
New: [MMask] Support any planar input video formats e.g. greyscale, Planar RGB.
Input clip can even be of different bit depth or format from vector's original format
For kind==5 where U and V is filled, the greyscale option is not allowed
Mod: [MMask] Faster: request source frame only for kind=5.
Fix: [MxxxxFPS,MMask]: MakeVectorOcclusionMaskTime garbage in bottom blocks (30 hrs of debugging)
Fix: [MMask] bottom padding garbage for padded frame dimension
Fix: [MMask] proper 10+ bits scene change values (for default: 1023, 4095, 16383, 65535. Was: 65535)
Parameter is still in 8-bit range
Fix: [MRecalculate] prevent overflow during thSAD scaling in 16 bits or large block sizes (32, 48...)
Fix: [DepanEstimate] Giving wrong motion instead of scene change detection
Fix: [MAnalyze] Possible overflow in MAnalyze 8 bit, block size 48x48 and above.
Overflow-safe predictor recalc for big block sizes
New: [General] Add block size 12x3 for SAD, allow 6x24

Mod: [Internal] Reorganized 10-16 bit SAD simd intrinsics, faster 8-12% for BlkSize 12-32
2.7.18.22 (20170512)
Fix: 10-16 bit: DCT buffer possible overflow
Fix: DCT is fast again for non 8x8 blocksizes. Regression since 2.7.5.22.
New: Chroma SAD is now always half of luma SAD, regardless of video format.
Without this: YV24's luma:chroma SAD ratio is 4:8 instead of 4:2 (of YV12)
New: MAnalyze, MRecalculate new parameter: "scaleCSAD" integer, default 0
Fine tune chroma SAD weight relative to luma SAD.
ScaleCSAD values for luma:chroma SAD ratio
-2: 4:0.5
-1: 4:1
0: 4:2 (default, same as the native ratio for YV12)
1: 4:4
2: 4:8
New: Block sizes 64, 48, 24, 12, 6
MAnalyze/MRecalculate new block sizes (SATD support mod4 sizes)

Note: some smaller block sizes can only be available in 4:4:4 formats, due to block size division (chroma subsampling)
New: All block sizes are supported in MDegrain1-6, MDegrainN, and MScaleVect
New: Changed to 2017 version of asm files for 8 bit SAD/SATD functions from x265 project.
Added not implemented asm code for 12, 24, 48 sizes
For some block sizes AVX2 and SSE4 is supported (AVX2 if reported under AviSynth+)
e.g. BlkSize 32 is faster now.
New: MMask SAD Mask to give identical weights for other-than-YV12 formats, e.g. for YV24
MvTools2 2.7.17.22 (20170426)
Fix: Regression in 2.7.16.22: MDegrain right pixel artifacts on non-modulo 16 widths
Misc: MMask, mode SADMask output is normalized further by video subsampling (YV16/YV24 has larger SAD value due to bigger chroma part that classic YV12)
