  37.      ggggllllIIIInnnnddddeeeexxxx updates the current (single-valued) color index.  It takes one
  38.      argument, the new value for the current color index.
  39.  
  40.      The current index is stored as a floating-point value. Integer values are
  41.      converted directly to floating-point values, with no special mapping.
  42.      The initial value is 1.
  43.  
  44.      Index values outside the representable range of the color index buffer
  45.      are not clamped.  However, before an index is dithered (if enabled) and
  46.      written to the frame buffer, it is converted to fixed-point format.  Any
  47.      bits in the integer portion of the resulting fixed-point value that do
  48.      not correspond to bits in the frame buffer are masked out.

  51.      ggggllllIIIInnnnddddeeeexxxxuuuubbbb and ggggllllIIIInnnnddddeeeexxxxuuuubbbbvvvv are available only if the GL version is 1.1 or
  52.      greater.
  53.  
  54.      The current index can be updated at any time.  In particular, ggggllllIIIInnnnddddeeeexxxx can
  55.      be called between a call to ggggllllBBBBeeeeggggiiiinnnn and the corresponding call to ggggllllEEEEnnnndddd.
