Subject: struct sw_span is again allocated on the stack, but the arrays of
 span data are broken out into a new struct span_arrays which is allocated
 per-context (to avoid huge stack allocations - a problem on Windows). This
 lets us use span.redStep instead of span->redStep (for example) to hopefully
 get slightly better performance in the triangle functions.
