Neil Roberts ff48f3b174 journal: Always keep a pointer back to the framebuffer
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.
