  12  * Concepts:
  13  *   15 = RGB15 or BGR15
  14  *   16 = RGB16 or BGR16
  15  *   24 = RGB24 or BGR24
  16  *   32 = RGB32 or BGR32
  17  * I420 = YCbCr where Y is issued for each pixel,
  18  *                    followed by Cr for 2x2 pixels,
  19  *                    followed by Cb for 2x2 pixels
  20  * YUY2 = YCbCr where for each pixel, Y is issued,
  21  *                    followed by Cr for 2x1 pixels (if even pixel)
  22  *                             or Cb for 2x1 pixels (if odd pixel)
  23  *
  24  * Note: Not all functions honor the swap_red_blue setting.
