Previously when adding a quad to the journal it would assume the journal belongs to the framebuffer at the top of the framebuffer stack and store a reference to that. We eventually want to get rid of the framebuffer stack so we should avoid using it here. The journal now takes a pointer back to the framebuffer in its constructor and it always retains the pointer. As was done previously, the journal still does not take a reference on the framebuffer unless it is non-empty so it does not create a permanent circular reference.
