 * @Short_description: A tag that can be applied to text in a GtkSourceBuffer

 * @Title: GtkSourceTag

 * @See_also: #GtkSourceBuffer

 *

 * #GtkSourceTag is a subclass of #GtkTextTag that adds properties useful for

 * the GtkSourceView library.

 *

 * If, for a certain tag, #GtkTextTag is sufficient, it's better that you create

 * a #GtkTextTag, not a #GtkSourceTag.
