21     Description: This implements the gtk+ GUI for the virtual turntable
22                  class implemented in tX_vtt.cc. This code is not in tX_vtt.cc
23                  for mainly to keep the GUI code divided from the audio-rendering
24                  code and as gtk+ callback to C++ method call wrapper.
25                  
26     Changes:
27     
28     before 11-26-2001: too many changes.
29     
30     11-26-2001: applied Adrian's solo/mute patch - Alex
31     
32     11-27-2001: modified solo/mute to use the set_mix_mute/solo function
33                 of the vtts. The previous approach messed up the sequencer
34                 and more. Removed some old unnecessary code, too.
