I'll probably release this one of these days. It needs some cleaning
up and mimimal packaging and documentation. It uses libclxclient
which for drawing is just a very thin C++ layer on top of X11.

The main X11 call used are:

 XCopyArea()         scroll  
 XFillRectange()     clear the new part
 XDrawSegments()     plot the new lines

Update speed is fixed at Fsample / 480 (for Fsample <= 48 kHz),
modified slightly by a DLL to adapt to the actual sample rate.
