Hi.

We have a problem with the sample program perfly. If we try to load
a dxf-file parts of the geometry are missing. One of the problems
shows up if we use an dxf-file with 2D grid. From flat polygons
(squares) we get two triangles from which one is not drawn. This may
be backface culling. Is there any way to turn this off? Also these 2
triangles are arranged incorrectly so that the resulting polygon does
not look like a square.

        Baljit and Steffen
