> The DXF format polylines and lwpolylines have a 'flags' field of which bit 0
> indicates if the polyline/lwpolyline is to be closed or open. This flags
> field is correctly read during the import but in the conversion to board
> segments, was previously not used.

> This patch remembers the start of the polyline and then after processing all
> segments it check bit 0
> of the flags field. If the bit is set to 1, an extra closing segment is
> generated between the last segment endpoint and the remembered polyline
> start point.
>
> Also attached a ellipses DXF in R12 format exported from LibreCAD that I
> used to test this patch. It clearly shows the open segment when imported.
> With the patch in place the DXF imports correctly shows as a closed
> polyline.
