NAME
	  glGetPixelMapfv, glGetPixelMapuiv, glGetPixelMapusv -	return
	  the specified	pixel map


     C SPECIFICATION
	  void glGetPixelMapfv(	GLenum map,
				GLfloat	*values	)
	  void glGetPixelMapuiv( GLenum	map,
				 GLuint	*values	)
	  void glGetPixelMapusv( GLenum	map,
				 GLushort *values )


     PARAMETERS
	  map	  Specifies the	name of	the pixel map to return.
		  Accepted values are GL_PIXEL_MAP_I_TO_I,
		  GL_PIXEL_MAP_S_TO_S, GL_PIXEL_MAP_I_TO_R,
		  GL_PIXEL_MAP_I_TO_G, GL_PIXEL_MAP_I_TO_B,
		  GL_PIXEL_MAP_I_TO_A, GL_PIXEL_MAP_R_TO_R,
		  GL_PIXEL_MAP_G_TO_G, GL_PIXEL_MAP_B_TO_B, and
		  GL_PIXEL_MAP_A_TO_A.

	  values  Returns the pixel map	contents.

     DESCRIPTION
	  See the glPixelMap reference page for	a description of the
	  acceptable values for	the map	parameter.  glGetPixelMap
	  returns in values the	contents of the	pixel map specified in
	  map.	Pixel maps are used during the execution of
	  glReadPixels,	glDrawPixels, glCopyPixels, glTexImage1D, and
	  glTexImage2D to map color indices, stencil indices, color
	  components, and depth	components to other values.

	  Unsigned integer values, if requested, are linearly mapped
	  from the internal fixed or floating-point representation
	  such that 1.0	maps to	the largest representable integer
	  value, and 0.0 maps to 0.  Return unsigned integer values
	  are undefined	if the map value was not in the	range [0,1].

	  To determine the required size of map, call glGet with the
	  appropriate symbolic constant.

     NOTES
	  If an	error is generated, no change is made to the contents
	  of values.

     ERRORS
	  GL_INVALID_ENUM is generated if map is not an	accepted
	  value.

	  GL_INVALID_OPERATION is generated if glGetPixelMap is
	  executed between the execution of glBegin and	the
	  corresponding	execution of glEnd.
