Change log
MvTools2 2.7.14.22 (20170206)
  Fix: MAnalyze divide=2 showed "vector clip is too small"
       (inherited from 2.6.0.5, sanity check was done but length was not filled for divideextra data)
  Fix: MFlow access violation in internal mv resizer when resizing factor was big (MCaWarpSharp3 4x supersampling case)
       (bug introduced in upstream 2.5.11.22)

MvTools2 2.7.13.22 (20170201)
  Fix: MDegrain1-6,N 10-16 bit thSCD scaling

MvTools2 2.7.12.22 (20170120)
  New: Faster SATD (dct=5..10) 8 bit: updated x264 function selectors, SSE2/4/AVX/AVX2
       +10% speed for a whole typical MDegrain3 process on my i7-3770
  New: Much Faster SATD (dct=5..10) 10-16 bit: SSE2/SSE4 instead of C 
       +50% speed for a whole typical MDegrain3 process (which is approx half speed of 8 bit)

MvTools2 2.7.11.22 (20170116)
  New: MDegrain6
  Mod: MDegrain1-6 SSE4 for 10-16 bit (was: C. 3-5% gain, wasn't bottleneck)

MvTools2 2.7.10.22
20161228 - Debug mode text fix for YV12 (bad text position on chroma planes)

MvTools2 2.7.9.22
20161220 - significantly faster
  Apply 2.5.11.9-svp analysis speedup, mainly when chroma involved

MvTools2 2.7.8.22
20161218 - YUY2 fixes
  Fix: YUY2 input access violation (regression after 2.7.0.22d)
  Fix: MDegrain: free up YUY2 planes only if not planar input (bug inherited from 2.5.11.22 MDegrain3)
       resulting in freeze at script exit

MvTools2 2.7.7.22
20161214 - optimizing a bit
- change some 8 bit SAD functions for the better
- separating bottleneck 8 bit/16 bit code paths in order not to use slower 
  int64 calculations for 8 bit, where there are no integer overflow problems
- more __forceinlines for helping the compiler
- general speed gain of 5-15% compared to 2.7.6.22, much reduced speed gap
  compared to the "classic" YV12 8 bit mvtools2 versions


MvTools2 2.7.6.22
20161204 - fixes and speedup

- Fix: sumLumaChange underflow (used for dct=2,6,9)
- MeanLumaChange scale for 10-16 bits (used for dct=2,6,9)
- Mask fix: 8 bit mask resizer bug in SIMD intrinsics - Thx real.finder
- Help vs2015 with some __forceinline directives to recognize the truth.
- Some other optimizations (bitshift instead of div or mul)
- FFTW DCT: SSE2/SSE4 FloatToBytes, BytesToFloat
- 16 bit SAD: a few optimizations in SSE2, AVX-coded SSE2 and AVX2 codepath
- Fix: dctmode=1,2: pixel distance was not corrected for 16 bit pixel sizes
