remove unused call to get_last_line()

2000-12-14  Havoc Pennington  <hp@redhat.com>

	* gtk/gtktextbtree.c (_gtk_text_btree_validate_line): remove
	unused call to get_last_line()

	* gtk/gtkobject.c (gtk_object_add_arg_type): add G_TYPE_POINTER
	here until boxed is working (and maybe after that - we should
	really not gratuitously break old code)

	* gtk/gtktexttag.c (gtk_text_tag_class_init): add commented-out
	specific types for font_desc and tabs args, move them to
	GTK_TYPE_POINTER for now, waiting on g_param_spec_boxed() to get
	fixed. Move GdkColor args to GTK_TYPE_POINTER also.

	* gtk/gtktextbuffer.c (gtk_text_buffer_class_init): temporarily
	use GTK_TYPE_POINTER for signal signatures as a hack-around

	* gtk/gtk-boxed.defs: Add boxed types for PangoFontDescription and
	PangoTabArray

	* gtk/gtktextlayout.c (line_display_iter_to_index):
	make static
	(line_display_index_to_iter): make static

	* gtk/gtktextbuffer.c (gtk_text_buffer_class_init): fix marshaller
	to marshal a string not a boxed

	* gtk/gtkmarshal.list: add marshaller for GtkTextBuffer:insert_text

	* gtk/testtext.c (fill_file_buffer): don't use g_utf8_next_char
	since the UTF-8 isn't validated yet

	* gtk/gtktextsegment.c (char_segment_check_func): don't require
	lines to end in '\n'

	* gtk/gtktextview.c (gtk_text_view_move_cursor): update to use
	forward_to_delimiters, and grapheme boundaries
	(gtk_text_view_delete_from_cursor): properly handle non-newline
	delimiters, and grapheme boundaries

	* gtk/gtktextiter.c (gtk_text_iter_forward_to_newline): rename
	to gtk_text_iter_forward_to_delimiters, and make it work properly
	if empty lines end with a character other than '\n'

	* gtk/gtktextiter.h, gtk/gtktextiter.c: Add movement by cursor
	position
