fb: add frame_{width,height} to fb_fragment_t
Modules need to know the overall dimensions of the frame the fragment they're rendering is part of. Previously it wasn't really necessary since the fragments supplied to the modules had always been the full page, but that's changing. This commit also changes the julia module to use the frame dimensions, others will need updating as well.
