* struct sw_span is again allocated on the stack, but the arrays of spanBrian Paul2002-08-071-6/+7
| | | | | | | 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.

* Converted line drawing over to new span code, pb no longer used.Brian Paul2002-02-021-30/+1
| | | | | Big clean-up of line drawing code. Removed many obsolete span processing functions.
