Code Issues Activity Actions

WindowServer+MenuApplets: Move the "Audio" applet to its own program

Browse source 
This patch introduces the second MenuApplet: Audio. To make this work,
menu applet windows now also receive mouse events.

There's still some problem with mute/unmute via clicking not actually
working, but the call goes from the applet program over IPC to the
AudioServer, where something goes wrong with the state change message.
Need to look at that separately.

Anyways, it's pretty cool to have more applets running in their own
separate processes. :^)
