      Allow negative height when ConvertToI420/ARGB is called with NV12/NV21 · a8aa921c
      Robert Bares authored
      ConvertToI420 and ConvertToARGB support the use of a negative height
      parameter to flip the image vertically. When converting from NV12 or
      NV21 this parameter was misinterpreted, resulting in invalid output.
      This CL introduces the use of abs_src_height to correctly calculate
      the location of the source UV plane.
      
      The sign of crop_height is not used, to reduce confusion ConvertToI420
      and ConvertToARGB no longer accept negative crop height.
      
      Unit tests for Android420ToI420 are updated to fix miscalculation of
      src_stride_uv, fix incorrect pixel strides, and to test inversion.
      New unit tests are included to test inversion for ConvertToARGB,
      ConvertToI420, Android420ToARGB, and Android420ToABGR.
      For consistency the test NV12Crop is renamed ConvertToI420_NV12_Crop.
