rtaudio with asio/wasapi in of0.9x

/** quick hack to pick asio/wasapi in OF0.9x  this won't be necessary in of1.0 **/


/** step 1: open libs/openFrameworks/sound/ofRtAudioSoundStream.cpp **/

#include <wchar.h>

bool checkForAsioArgs() {
    LPWSTR *szArgList;
    int argCount;

    szArgList = CommandLineToArgvW(GetCommandLine(), &argCount);
    if (szArgList != NULL) {
        for (int i = 0; i < argCount; i++) {
            if (wcscmp(szArgList[i], L"asio")==0) {
                return true;
            }

#define OF_RTAUDIO_API (of_rtaudiostream_use_asio?RtAudio::Api::WINDOWS_ASIO:RtAudio::Api::WINDOWS_WASAPI)


/** step 2: there are two occurences of new RtAudio() in that same file. use instead: **/
new RtAudio(OF_RTAUDIO_API)


/** step 3: now build the solution (don't run it!).  **/

/** step 4: create a shortcut
In windows explorer right click on myApp/bin/myApp.exe and create a new shortcut.
rename it to "myApp.exe - Asio" so it's easy to find.

edit the shortcut. at the end of shortcut target add an 'asio' argument.
for me the target is now:
    C:\Users\be\Desktop\of_v0.9.3_vs_release\apps\myApps\sketchyscope\bin\sketchyscope.exe asio

don't worry about the absolute path. windows knows how to fix things if it gets moved around.

/** step 5: double click your shortcut. **/
