The depth/stencil-Image has no pixel data after the rendering.
The colorimage works fine.
Here is my code for the FBO setup:

Do I miss something there?
I thought everything is similar to the colorimage, so it has to work
out, but depthimage->isValid() returns false.
hm, it appears readback was only implemented for color attachments :(
The attached patch should change it to also handle depth and stencil
attachments (including combined ones). Can you give it a try and see if
it works for you, thanks!
Cheers,
Carsten
