If the GL is in color index mode, each index that is read from this buffer is converted to a fixed-point format with an unspecified number of bits to the right of the binary point. Each index is then shifted left by <code class="constant">GL_INDEX_SHIFT</code> bits, and added to <code class="constant">GL_INDEX_OFFSET</code>. If <code class="constant">GL_INDEX_SHIFT</code> is negative, the shift is to the right. In either case, zero bits fill otherwise unspecified bit locations in the result. If <code class="constant">GL_MAP_COLOR</code> is true, the index is replaced with the value that it references in lookup table <code class="constant">GL_PIXEL_MAP_I_TO_I</code>.
