  ``RENDERDOC_YUVAChannels`` will be filled out an index indicating where each channel comes from in the source textures. The order is ``.x`` for ``Y``, ``.y`` for ``U``, ``.z`` for ``V`` and ``.w`` for ``A``.
  -The indices for channels in the first texture in the normal 2D slot are ``0, 1, 2, 3``. Indices from ``4`` to ``7` indicate channels in the second texture, and so on.

  If a channel is not present, e.g. alpha is commonly not available, it will be set to ``0xff == 255``.
