<tt>glutGetColor</tt> retrieves a red, green, or blue component for a given color index colormap entry for
the current window's logical colormap. The current window should be a color index window. cell should be zero or
greater and less than the total number of colormap entries for the window. For valid color indices, the value returned
is a floating point value between 0.0 and 1.0 inclusive. <tt>glutGetColor</tt> will return -1.0 if the
color index specified is an overlay's transparent index, less than zero, or greater or equal to the value returned by
<tt>glutGet(GLUT_WINDOW_COLORMAP_SIZE)</tt>, that is if the color index is transparent
or outside the valid range of color indices.
