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

  52.      ffffggggllllIIIInnnnddddeeeexxxxuuuubbbb and ffffggggllllIIIInnnnddddeeeexxxxuuuubbbbvvvv are available only if the GL version is 1.1 or
  53.      greater.
  54.  
  55.      The current index can be updated at any time.  In particular, ffffggggllllIIIInnnnddddeeeexxxx
  56.      can be called between a call to ffffggggllllBBBBeeeeggggiiiinnnn and the corresponding call to
