XlibRGB

<!-- ##### SECTION Short_Description ##### -->
Functions for rendering RGB buffers to X drawables.

<!-- ##### SECTION Long_Description ##### -->
  <para>
    The XlibRGB set of functions is a port of the GdkRGB library to
    use plain Xlib and X drawables.  You can use these functions to
    render RGB buffers into drawables very quickly with high-quality
    dithering.

  <para>
    These values are used to specify which dithering method should be
    used.  <symbol>XLIB_RGB_DITHER_NONE</symbol> will use no dithering
    and simply map the colors in an RGB buffer to the closest colors
    that the display can provide.
    <symbol>XLIB_RGB_DITHER_NORMAL</symbol> will provide dithering
    only on pseudocolor displays.
    <symbol>XLIB_RGB_DITHER_MAX</symbol> will provide dithering on
    pseudocolor and 16-bit truecolor or &ldquo;high color&rdquo;
    displays.
  </para>

@XLIB_RGB_DITHER_NONE: Specifies no dithering.
@XLIB_RGB_DITHER_NORMAL: Specifies dithering only on pseudocolor
displays.
@XLIB_RGB_DITHER_MAX: Specifies dithering on high color displays.
