PARAMETERS
       target  The   target   color    table.     Must    be    GL_COLOR_TABLE,
               GL_POST_CONVOLUTION_COLOR_TABLE,
               GL_POST_COLOR_MATRIX_COLOR_TABLE,          GL_PROXY_COLOR_TABLE,
               GL_PROXY_POST_CONVOLUTION_COLOR_TABLE,
               GL_PROXY_POST_COLOR_MATRIX_COLOR_TABLE.

       pnam    The symbolic name of a color lookup table  parameter.   Must  be
               one      of      GL_COLOR_TABLE_BIAS,      GL_COLOR_TABLE_SCALE,
               GL_COLOR_TABLE_FORMAT,                     GL_COLOR_TABLE_WIDTH,
               GL_COLOR_TABLE_RED_SIZE,              GL_COLOR_TABLE_GREEN_SIZE,
               GL_COLOR_TABLE_BLUE_SIZE,             GL_COLOR_TABLE_ALPHA_SIZE,
               GL_COLOR_TABLE_LUMINANCE_SIZE, or GL_COLOR_TABLE_INTENSITY_SIZE.

       _param3 A  pointer to an array where the values of the parameter will be
               stored.

DESCRIPTION
       Returns parameters specific to color table target.

       When  pnam  is  set  to  GL_COLOR_TABLE_SCALE  or   GL_COLOR_TABLE_BIAS,
       glGetColorTableParameter  returns  the color table scale or bias parame‐
       ters for the table specified by target.  For these queries, target  must
       be    set   to   GL_COLOR_TABLE,   GL_POST_CONVOLUTION_COLOR_TABLE,   or
       GL_POST_COLOR_MATRIX_COLOR_TABLE and _param3 points to an array of  four
       elements,  which receive the scale or bias factors for red, green, blue,
       and alpha, in that order.

       glGetColorTableParameter can also be used to  retrieve  the  format  and
       size  parameters for a color table. For these queries, set target to ei‐
       ther the color table target or the proxy color table target.  The format
       and size parameters are set by glColorTable.

       The  following  table  lists  the format and size parameters that may be
       queried.  For each symbolic constant listed below for pnam, _param3 must
       point to an array of the given length, and receive the values indicated.

          ───────────────────────────────────────────────────────────────────
          Parameter                       N   Meaning
          ───────────────────────────────────────────────────────────────────
          GL_COLOR_TABLE_FORMAT           1   Internal format (e.g. GL_RGBA)
          GL_COLOR_TABLE_WIDTH            1   Number of elements in table
          GL_COLOR_TABLE_RED_SIZE         1   Size of red component, in bits
          GL_COLOR_TABLE_GREEN_SIZE       1   Size of green component
          GL_COLOR_TABLE_BLUE_SIZE        1   Size of blue component

       GL_INVALID_OPERATION  is  generated  if glGetColorTableParameter is exe‐
       cuted between the execution of glBegin and the  corresponding  execution
       of glEnd.
