2008-08-25
----------
- first Linux port!!! - compilable with wxGTK-2.6.4 wth GTK2 and
  UNICODE; a plenty of problems:
   - GEN gauges do not work as expected
   - glitches in generator
   - wxTextCtrls do not react to ENTERs
- SA - variable FFT length
- SA - right channel is added
- SA - averaging of FFT values introduced

2008-08-22
----------
- renamed OScopeCtrl->CtrlOScope; double buffering and some other features
  added
- #define for switch XScale to microseconds/div - but a lot of problems with
  strange modulation

----------
- rewrite of audio driver started - RtAudio will be used now

2008-08-15
----------
- added rectangular, triangle, saw generators
- added auto calibration of Y scale ; offset is not changing
- prepared for load/save of configuration
- added menu accelerators

2008-06-06
----------
- triggering completely changed; currently missing control of trigger
  level and trigger hysteresis
- changed description of X scale and X resolution
- in Makefile.gcc changed directory delimiters in "clean" target

2008-06-04
----------
- Added text controls to set generator frequency more preciously
- phase between L and R channels is now in degrees (before it was radians)
