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.
