"instance" is the instance that owns the signal in question... i.e. if
you connected to "value-changed" on an adjustment... then the pointer
to *that* adjustment is the instance you must pass in....

You can use it to prevent feedback in your application when you are
performing resets or manually setting the values to some predefined states.
