2001-03-07 Havoc Pennington <hp@redhat.com> * gtk/gtktextview.c (invalidated_handler): use PRIORITY_VALIDATE * gtk/gtktextview.h (GTK_TEXT_VIEW_PRIORITY_VALIDATE): add this here, bug #50368; changed to be GDK_PRIORITY_REDRAW + 5, instead of GDK_PRIORITY_REDRAW + 1, so you can insert stuff in between the validation and the redraw which is higher priority than the validation.
