[Interest] [Qt3D] Troubles to migrate to Qt5.7rc

[Xavier Bigand]

Thank you, I couldn't reply earlier, but I do similar changes than you to
fix the issue.

Now I think that I have to make our app able to run in the main thread
instead than in the rendering one. Our current engine isn't threaded, so we
force Qt to use the main thread for the qml rendering.
With Qt3D it seems giving some stability issues. I have to fix stability
before continuing to implement missing rendering issue on top of Qt3D.
