    <summary>Describes a particular video hardware display format.</summary>
    <remarks>
      <para>
	A Gdk.Visual describes a particular video hardware display
	format. It includes information about the number of bits used
	for each color, the way the bits are translated into an RGB
	value for display, and the way the bits are stored in
	memory. For example, a piece of display hardware might support
	24-bit color, 16-bit color, or 8-bit color; meaning
	24/16/8-bit pixel sizes. For a given pixel size, pixels can be
	in different formats; for example the "red" element of an RGB
	pixel may be in the top 8 bits of the pixel, or may be in the
	lower 4 bits.
      </para>
      <para>
	Usually you can avoid thinking about visuals in GTK+. Visuals
	are useful to interpret the contents of a <see cref="T:Gdk.Image" />, but you should avoid GdkImage precisely
	because its contents depend on the display hardware; use <see cref="T:Gdk.Pixbuf" /> instead, for all but the most low-level
	purposes.  Also, anytime you provide a <see cref="T:Gdk.Colormap" />, the visual is implied as part of the
	colormap (<see cref="P:Gdk.Colormap.Visual" />), so you won't
	have to provide a visual in addition.
      </para>
      <para>
	There are several standard visuals.  The visual returned by
	<see cref="P:Gdk.Visual.System" /> is the system's default
	visual.  <see cref="P:Gdk.Rgb.Visual" /> return the visual most
	suited to displaying full-color image data. If you use the
	calls in <see cref="T:Gdk.RGB" />, you should create your
	windows using this visual (and the colormap returned by <see cref="P:Gdk.Rgb.Colormap" />).
      </para>
      <para>
	A number of functions are provided for determining the "best"
	available visual.  For the purposes of making this
	determination, higher bit depths are considered better, and
	for visuals of the same bit depth, <see cref="E:Gdk.VisualType.PseudoColor" /> is preferred at 8bpp,
	otherwise, the visual types are ranked in the order of
	(highest to lowest) <see cref="E:Gdk.VisualType.DirectColor" /><see cref="E:Gdk.VisualType.TrueColor" />, <see cref="E:Gdk.VisualType.PseudoColor" />, <see cref="Gdk.VisualType.StaticColor" />, <see cref="Gdk.VisualType.Grayscale" />, then
	<see cref="E:Gdk.VisualType.StaticGray" />.
