Make AALinearizingConvexPathRenderer able to handle stroke and fill

This is intended to catch stroke-and-fill convex paths with potentially small stroke widths (e.g., .1).

It does have the disconcerting side effect of changing bevel-joined stroke-and-filled degenerate-single-line-rects into plain rects (w/o triangular end-caps).
