* gtk/gtkspinbutton.h gtk/gtkspinbutton.c gtk/testgtk.c:
- Bug fix for precision problem causing occasional double emission
of "value_changed" signal (hopefully works now).
- API change (should be binary compatible) :
new enum GtkSpinType; modified gtk_spin_button_spin to use it.
Modified cursor example appropriately.
To spin by something other than step_/page_increment, use
gtk_spin_button_spin (spin, GTK_SPIN_USER_DEFINED, increment).
- Made GTK_SHADOW_NONE the default. ;)
- Fixed casting of GtkAdjustment* to GtkWidget* in
gtk_spin_button_value_changed.
