- * to give tags a name; pass NULL for the name to create an
- * anonymous tag.
- *
- * In any real app, another useful optimization would be to create
- * a GtkTextTagTable in advance, and reuse the same tag table for
- * all the buffers with the same tag set, instead of creating
- * new copies of the same tags for every buffer.
- *
- * Tags are assigned default priorities in order of addition to the
- * tag table. That is, tags created later that affect the same text
- * property affected by an earlier tag will override the earlier
- * tag. You can modify tag priorities with
- * gtk_text_tag_set_priority().
