AddNoise example for C++ 5.0 and later

This example adds red noise and redisplays the bitmap.

   ILEADRasterProcess *pRasterProc=NULL;
   CoCreateInstance(CLSID_LEADRasterProcess, NULL, CLSCTX_ALL,
                    IID_ILEADRasterProcess, (void**)&pRasterProc);
   pRasterProc->AddNoise(m_LEADRasterView1.GetRaster(), 500, CHANNEL_RED);
   pRasterProc->Release();
   m_LEADRasterView1.ForceRepaint();
