        * gtk/gtktipsquery.c: we make an active server grab now, this way we
        can change the cursor globally and don't need to tweak event masks
        of other windows.

        * gtk/gtkframe.c (gtk_frame_style_set): recompute label size.

        * gtk/gtkwidget.h:
        * gtk/gtkwidget.c:
        New signal GtkWidget::style_set to be emitted when a widget's style
        changed. New flag GTK_RC_STYLE to indicate whether an rc lookup has
        been perfomed for the widget.
        (gtk_widget_ensure_style): New function.
        (gtk_widget_set_rc_style): New function.

        * docs/styles.txt: new file.
