\brief This example shows how to create a minimal QOpenGLWidget based
application with stereoscopic rendering support.
\note Support for stereoscopic rendering has certain hardware requirements,
such as, a graphics card with stereo support, 3D glasses and specific
monitors.
\note This example renders two images to two separate buffers. When you
view the images through 3D glasses, they give a 3D holographic effect.

The above image is what will be rendered to the right buffer.

your graphics card needs stereo support.
\section1 Setting the correct surface flag
To enable stereoscopic rendering you need to set the flag
QSurfaceFormat::StereoBuffers globally. Just doing it on the widget is not enough
