Open Scene Graph: Render scene to image

OSG ships with many examples including several applications that renders the scene to image, for instance OsgAutoCapture, and OsgScreenCapture.

Whilst these applications are information rich, yet they lack sufficient conciseness and are not right to the point sometimes. It took me hours to get what I need, and for my specific task, I just need such a simple class OsgSnapshotHelper:

void Capture(osgViewer::Viewer* pViewer, std::string outputImagePath)
OsgSnapshotHelper* osh = new OsgSnapshotHelper(pViewer);
delete osh;
osh = NULL;
std::cout << Ending Capture: << outputImagePath  << std::endl;
