1. Fix a longstanding (and evidently latent) bug in widegraph.cpp.
2. Add basic proof-of-concept code that uses QAudioInput instead of PortAudio for sound input. By default, this test code is not active, and it compiles using PortAudio. To compile using QAudio, uncomment the line #DEFINES += QAUDIO_INPUT in wsjtx.pro. Note that device selection in the QAudio code is presently hard-wired to use the default input device. You can change this choice on line 267 in soundin.cpp. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@3510 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
