DWF polytriangles render poor in AGG

Description

When AGG renders a DWF polytriangle it renders each subtriangle independently rather than rendering the triangle strip as one call. Due to AGG's antialiasing this causes the interior edges of the strip to be treated as boundaries and to be incorrectly rendered.

An image showing the defect is attached. This is for a polytriangle with two triangles. The map background was set to black to better show the issue.
