        * gdk/gdk.h:
        * gdk/gdkwindow.c: new function gdk_window_at_pointer() to retrive
        the current GdkWindow the pointer is on if there is any.

        * gtk/gtktable.c (gtk_table_init): preallocate a table with one row
        and one column, so we don't construction logic at all. changed a few
        (x < y - 1) to (x + 1 < y), to avoid failing evaluations due to
        unsigned int wraps.

        * gtk/gtkwidget.c (gtk_widget_set_parent): removed left over code
        portion, added an additional check for parent != widget.

        * more GtkType and macro fixups.
