Both will segfault with X library, cause it doesn't check coords.
So will be with linux-fb, cause gdk code doesn't check coords (isn't 
this a bug ?).
In Win32 code has checking, so it'll safe return with no warnings
in case you get out of image (this's probably the weird situation,
cause you will not know if you'll fail).
Hmm, win32 code looks very very very very *BAD*.

It has "input", "output", "value_changed", "change_value" signals. It's 
easy to
look inside "gtkspinbutton.c".
