Subject: [PATCH] Use board polygon instead of bbox for size

Board BBox uses the visible size of the board, which includes edge cut
thickness.  This is not appropriate for the Board characteristics.
Using the outline polygon gives accurate results and falls back to a
bounding box in the case where the outline is invalid
