  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.
