I would like to point out that hellowindow is also GLES 2.0 based. 
hellogl_es2 might have issues since it's creating an embedded QGLWidget 
and I'm not sure how good the support for multiple top-level widgets / 
windows is in the eglfs plugin.

Although I think hellogl_es might do the same thing...

Btw, qmlscene also uses GLES 2.0, and many people have had it running on 
the Pi. It's a less complicated case than the hellogl_* variants since 
it only creates a single QWindow.
