The FBO/offscreen examples (unit tests) render to FBO/texture, yes.
Using glReadPixels as shown in the unit tests works for all platforms,
however .. you may optimize it via PBO and using double buffering (at least).
I.e. if you want to stream some rendering to file, I would use 2-3 FBOs
w/ PBO (dma transfer) if available.
This has been discussed here for a while ..
