Emitted when a scroll action is performed on a range.
It allows an application to determine the type of scroll event
that occurred and the resultant new value. The application can
handle the event itself and return %TRUE to prevent further
processing. Or, by returning %FALSE, it can pass the event to
other handlers until the default GTK handler is reached.
The value parameter is unrounded. An application that overrides
the ::change-value signal is responsible for clamping the value
to the desired number of decimal digits; the default GTK
handler clamps the value based on [property@Gtk.Range:round-digits].
