    <summary>An object for rendering a single cell on a <see cref="T:Gdk.Drawable" /></summary>
    <remarks>
      <para>
	    The <see cref="T:Gtk.CellRenderer" /> is a base class of a set of objects used for rendering a cell to a <see cref="T:Gdk.Drawable" />.
		These objects are used primarily by the <see cref="T:Gtk.TreeView" /> widget, though they are not tied to them in any specific way.
		It is worth noting that <see cref="T:Gtk.CellRenderer" /> is not a <see cref="T:Gtk.Widget" /> and cannot be treated as such.
	  </para>
      <para>
	    The primary use of a <see cref="T:Gtk.CellRenderer" /> is for drawing a certain graphical elements on a <see cref="T:Gdk.Drawable" />.
		Typically, one <see cref="T:Gtk.CellRenderer" /> is used to draw many cells on the screen.
		To this extent, it is not expected that a <see cref="T:Gtk.CellRenderer" /> keep any permanent state around.
		Instead, any state is set just prior to use.
		Then, the cell is measured using <see cref="M:Gtk.CellRendererGetSize(Gtk.Widget,Gdk.Rectangle,System.Int32,System.Int32,System.Int32,System.Int32)" />.
		Finally, the cell is rendered in the correct location using <see cref="M:Gtk.CellRenderer.Render(Gdk.Window,Gtk.Widget,Gdk.Rectangle,Gdk.Rectangle,Gdk.Rectangle,Gtk.CellRendererState)" />.
	  </para>
      <para>
	    There are a number of rules that must be followed when writing a new <see cref="T:Gtk.CellRenderer" />.
		First and foremost, it is important that a certain set of properties will always yield a <see cref="T:Gtk.CellRenderer" /> of the same size, barring a <see cref="T:Gtk.Style" /> change.
		The <see cref="T:Gtk.CellRenderer" /> also has a number of generic properties that are expected to be honored by all children.

        <remarks>
          The three passed-in rectangles are areas of <paramref name="window" />.
		  Most renderers will draw within <paramref name="cell_area" />;
		  <paramref name="background_area" /> includes the blank space around the cell, and also the area containing the tree expander; so the <paramref name="background_area" /> rectangles for all cells tile to cover the entire window.
		  <paramref name="expose_area" /> is a clip rectangle.

        <remarks>
          <para>
	    The intended use of this signal is to do special setup on editable cell, e.g. adding a <see cref="T:Gtk.EntryCompletion" /> or setting up additional columns in a <see cref="T:Gtk.ComboBox" />.
	  </para>
          <para>
	    Note that GTK# doesn't guarantee that cell renderers will continue to use the same kind of widget for editing in future releases, therefore you should check the type of the cell before doing any specifi setup.
