til: support multi-pass rendering
Modules can now use the til_module_t.finish_frame() return value to trigger re-rendering by returning 1, returning 0 finishes the frame. A smattering of til_module_t.finish_frame() implementations were largely mechanically updated to match this change by returning 0, since nothing actually uses multi-pass rendering yet. The impetus for this is experimenting with the flow module doing two passes of threaded rendering per frame. A first pass to sample the flow field and update the elements, per-cpu, but drawing nothing. Then a second pass to render the elements in a tiled manner.
