Erasing bug in GTK examples/gtkdial

[BJerrick easystreet com]

    The pointer in examples/gtkdial (gtk+-1.2.6 through gtk+-snap20000810,
at least) doesn't erase completely when moved.  This is due to two
bugs in the widget's code, gtkdial.c .

    A fix for both is below.  The added comment explains the first.
The second changes the 'fill' argument of the gtk_draw_polygon() that
does the erasing to match that used for drawing (TRUE, i.e., filled).
