Avoid recreating pangolayouts in GtkTextView on cursor movement (#435405,
2007-06-01 Yevgen Muntyan <muntyan@tamu.edu>
Avoid recreating pangolayouts in GtkTextView on cursor movement
(#435405, Behdad Esfahbod).
* gtk/gtktextlayout.c:
* gtk/gtktextlayout.h: new GtkTextLayout method invalidate_cursors(),
and functions gtk_text_layout_invalidate_cursors() and
gtk_text_layout_cursors_changed(), to use when invalidation is due
to moved marks or changed selection.
* gtk/gtktextbtree.c:
* gtk/gtktextbtree.h: use what's appropriate when invalidating layout.
* gtk/gtk.symbols: add new functions.
* README.in: added a note about changed GtkTextLayout API.
