Example code for testing
Changing the value of XKeyboardControl.bell_percent with XChangeKeyboardControl() affects the duration of bell ringing when XBell() is called.
It should affect the bell volume instead.
The value also interacts with XKeyboardControl.bell_duration in a strange way.
Reproducable: always + on different machines.
Initially reported as KDE-bug 118422.
