2004-12-08  Matthias Clasen  <mclasen@redhat.com>

	Fix #111031, reported by Padraig O'Briain:

	* gtk/gtktextlayout.h:
	* gtk/gtktextlayout.c (gtk_text_layout_get_iter_at_position):
	Add a variant of gtk_text_layout_get_iter_at_pixel() which
	returns the character at the position, not the closest
	cursor position.

	* gtk/gtktextview.h:
	* gtk/gtktextview.c (gtk_text_view_get_iter_at_position):
	Add a variant of gtk_text_view_get_iter_at_location() which
	returns the character at the position, not the closest
	cursor position.
