Add a new method, gboolean want_null_motion(), that tells if the brush 

1999-08-30  Tor Lillqvist  <tml@iki.fi>

* app/gimpbrush.h (GimpBrushClass): Add a new method, gboolean
want_null_motion(), that tells if the brush wants to be painted
when we don't know the direction yet. This is needed (so far) by
brush pipes that select the brush based on direction.

* app/gimpbrush.c: Implement above method returning always TRUE.

* app/gimpbrushpipe.c: Here, implement it returning FALSE or TRUE
on whether the brush pipe has any angular (direction) dependent
dimension or not.

* app/paint_core.c (paint_core_button_press): Call the method
if current point == last point.
