[Interest] Qt3D : Invalid mvp matrix with orthographic camera

[Xavier Bigand]

Sorry I found my bug, I forget to change the up vector.

Does the up vector be given with the view center to avoid this kind of
forget?

I also think that it can be helpfull if there was asserts on computations
resulting in nan values.
