This is a convenience function which simply creates a child anchor
with gtk_text_child_anchor_new() and inserts it into the buffer
with gtk_text_buffer_insert_child_anchor(). The new anchor is
owned by the buffer; no reference count is returned to
the caller of gtk_text_buffer_create_child_anchor().
