PaStreamFinishedCallback which is called anytime a PaCallback is exited with anything other than 0. (normal operation) paStreamFinishedCallback handles stopping the audio stream when we've run to the end of the current selection or the stream is stopped. * Add framesPerBuffer to paCallback debug output in preperation for dynamic buffers. * Set paPrimeOutputBuffersUsingStreamCallback in Pa_OpenStream to prime the output buffer using the callback rather than initing with empty space which is the default. * Indent paCallback decleration another level. Originally committed to SVN as r2807.
