New version 0.4.4

Got report that voiceapp no longer compiled correctly. Took a look at the code and made some fixes/enhancements, including:

• Optimized the way Analyzer and Scope draw themselves.
• -height option to set total window height
• -bg option to set background color
• -scope-lineh option to set height of Scope line (better visibility)
• -solid-scope option to draw Scope with lines from axis.
• -nospectrogram option to disable drawing of spectrogram (thanks for suggestion Michael P)
• ESC or 'Q' will now quit.
• Bugs:
  • Fixed compilation (thanks for report Michael P)
  • 255 vs 256 multiplying in color generation.
  • Limit vertical lines to window height
  • make -wlc option really do something useful

Height and width of window are a bit constrained because of the way we get and process data. If spectrogram is enabled, window must be at least M/2 pixels high where M is number of samples we push through FFT (-n -option, default 512). M/2 is also always width of Analyzer, and M is always width of Scope. Window width can be less that Analyzer+Scope, Scope will just not be fully drawn.

Note that even with such simplistic graphics VoiceApp will push your processor.
