Ensures that the contents of value comply with the specifications
set out by pspec. For example, a GParamSpecInt might require
that integers stored in value may not be smaller than -42 and not be
greater than +42. If value contains an integer outside of this range,
it is modified accordingly, so the resulting value will fit into the
range -42 .. +42.
