<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.CellRendererRender(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.

<param name="flags">an object of type <see cref="T:Gtk.CellRendererState"/></param>
<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.

Used by view widgets to determine the appropriate size for the <paramref name="cell_area"/> passed to gtk_cell_renderer_render().
If <paramref name="cell_area"/> is not <see langword="null"/>, fills in the x and y offsets (if set) of the cell relative to this location.
Please note that the values set in <paramref name="width"/> and <paramref name="height"/>, as well as those in <paramref name="x_offset"/> and <paramref name="y_offset"/> are inclusive of the xpad and ypad properties.
