Frank Barchard d011314f14 Revert "I210ToI420, InterpolatePlane_16, and ScalePlane Vertical-only asan fix" 
This reverts commit 60254a1d846a93a4d7559009004cdd91bcc04d82.

Reason for revert: breaks PaintCanvasVideoRendererTest.HighBitDepth

Original change's description:
> I210ToI420, InterpolatePlane_16, and ScalePlane Vertical-only asan fix
>
> - Add I210ToI420 to convert 10 bit 4:2:2 YUV to 4:2:0 8 bit
> - Add NEON InterpolateRow_16 for fast 10 bit scaling
> - When scaling up, set step to interpolate toward height - 1 to avoid buffer overread
> - When scaling down, center the 2 rows used for source to achieve filtering.
> - CopyPlane check for 0 size and return
>

README.md

libyuv is an open source project that includes YUV scaling and conversion functionality.

  • Scale YUV to prepare content for compression, with point, bilinear or box filter.
  • Convert to YUV from webcam formats for compression.
  • Convert to RGB formats for rendering/effects.
  • Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
  • Optimized for SSSE3/AVX2 on x86/x64.
  • Optimized for Neon on Arm.
  • Optimized for MSA on Mips.
