!todo fix `bordure rayonne` corners
!draw Argent, a bordure rayonne Gules
The top corners are messed up — there's a horizontal rayonne line, which is then overlapping the vertical rayonne lines, with the base of the rayonne pattern on the very edge of the field. I imagine it would work better if there was one long rayonne line running around the inner edge of the bordure, pointing outwards, and bending around the corners.
