 * @Short_description: Renders text in a cell
 * @Title: GtkCellRendererText
 *
 * A #GtkCellRendererText renders a given text in its cell, using the font, color and
 * style information provided by its properties. The text will be ellipsized if it is
 * too long and the #GtkCellRendererText:ellipsize property allows it.
 *
 * If the #GtkCellRenderer:mode is %GTK_CELL_RENDERER_MODE_EDITABLE,
 * the #GtkCellRendererText allows to edit its text using an entry.
