*: use fragment generator
Rather than laying out all fragments in a frame up-front in ray_module_t.prepare_frame(), return a fragment generator (rototiller_fragmenter_t) which produces the numbered fragment as needed. This removes complexity from the serially-executed prepare_frame() and allows the individual fragments to be computed in parallel by the different threads. It also eliminates the need for a fragments array in the rototiller_frame_t, indeed rototiller_frame_t is eliminated altogether.
