-- NOTES
--
-- Below `variadic` functions can't support by FFI:
-- gtk_text_buffer_insert_with_tags
-- gtk_text_buffer_insert_with_tags_by_name
-- gtk_text_buffer_create_tag
-- But above functions is not essential, we can use other functions do same work.
-- Example:
--
-- gtk_text_buffer_insert_with_tags equivalent to calling textBufferInsert,
-- then textBufferApplyTag on the inserted text.
--
-- gtk_text_buffer_insert_with_tags_by_name same as gtk_text_buffer_insert_with_tags,
-- just use textTagName handle tag name.
--
-- gtk_text_buffer_create_tag Equivalent to calling textTagNew
-- and then adding the tag to the buffer's tag table.
--
-- The following functions do not make sense due to Haskell's wide character
-- representation of Unicode:
-- gtk_text_buffer_get_iter_at_line_index
--
-- The function gtk_text_buffer_get_selection_bounds is only used to test
-- if there is a selection (see 'textBufferHasSelection').
