    lavfi/drawutils: improve colorspace support · 6c3a82f0
    rcombs authored
    - Introduce ff_draw_init2, which takes explicit colorspace and range
      args
    - Use lavu/csp and lavfi/colorspace for conversion, rather than the
      lavu/colorspace.h macros
    - Use the passed-in colorspace when performing RGB->YUV conversions
    
    The upshot of this is:
    - Support for YUV spaces other than BT601
    - Better rounding for all conversions
    - Particular rounding improvements in >8-bit formats, which previously
      used simple left-shifts
    - Support for limited-range RGB
    - Support for full-range YUV in non-J pixfmts
    
    Due to the rounding improvements, this results in a large number of
    minor changes to FATE tests.
