glGetPixelMapfv, glGetPixelMapuiv, glGetPixelMapusv -	return
the specified	pixel map

glGetPixelMapfv
	glGetPixelMapfv(map) -> values
glGetPixelMapuiv
	glGetPixelMapuiv(map) -> values
glGetPixelMapusv
	glGetPixelMapusv(map) -> values

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

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.

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.

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

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.
