[Interest] [Qt3D] Render depth images

Hi Raphael,

What you want is to do your rendering in 2 steps:

- Render your scene into a RenderTarget (with 2 attachments/textures,
one for color, one for depth)

- Render a full screen quad on which you display the depth texture.

We have some manual test in the Qt 3D sources that should show how to do


I hope that helps,
