Half-ass somewhat fix this function, so that scrolling to the insertion

	* gtk/gtktextlayout.c (gtk_text_layout_get_iter_location):
	Half-ass somewhat fix this function, so that scrolling to the
	insertion point works. Pango hacking is in the future to really
	fix it.

	* gtk/gtktextview.c (gtk_text_view_drag_data_get): Don't calculate
	length of data, no longer used.

	* gtk/gtktextbuffer.c (gtk_text_buffer_finalize): move destroy
	method contents in here, get rid of destroy method
	(gtk_text_buffer_insert_range): Fix some g_return_if_fail checks
	that were backward. Remove debug spew.
	(cut_or_copy): Make the clipboard work with insert_range to
	preserve tags and pixbufs, not just the primary selection.
