      This one is enclosed and contiguous though, the lines of the triangle end where the circular line starts. (The rest is just a drafting residue.)

        No, it is 2 contiguous regions. The line of separation is the bounding line of a “shape.”

        Otherwise, the entire whitespace outside of the region is also part of the shape, as is anything it touches.
