NAME
     glIndexd, glIndexf, glIndexi, glIndexs, glIndexdv,	glIndexfv, glIndexiv,
     glIndexsv - set the current color index



C SPECIFICATION
     void glIndexd( GLdouble c )
     void glIndexf( GLfloat c )
     void glIndexi( GLint c )
     void glIndexs( GLshort c )


PARAMETERS
     c	Specifies the new value	for the	current	color index.


C SPECIFICATION
     void glIndexdv( const GLdouble *c )
     void glIndexfv( const GLfloat *c )
     void glIndexiv( const GLint *c )
     void glIndexsv( const GLshort *c )


PARAMETERS
     c	  Specifies a pointer to a one-element array that contains the new
	  value	for the	current	color index.


DESCRIPTION
     glIndex updates the current (single-valued) color index.  It takes	one
     argument:	the new	value for the current color index.

     The current index is stored as a floating-point value.  Integer values
     are converted directly to floating-point values, with no special mapping.

     Index values outside the representable range of the color index buffer
     are not clamped.  However,	before an index	is dithered (if	enabled) and
     written to	the frame buffer, it is	converted to fixed-point format.  Any
     bits in the integer portion of the	resulting fixed-point value that do
     not correspond to bits in the frame buffer	are masked out.

NOTES
     The current index can be updated at any time.  In particular, glIndex can
     be	called between a call to glBegin and the corresponding call to glEnd.
