David Stadelmann a839dbb6d2 docs: document per-port shape overrides and rebuild manual
Document the per-port `shape`, `kind`, `size`, `stroke`, and `fill`
overrides in the ports dictionary of `element.elmt`, simplify the
`port-shape` parameter description, and update `port-shape-vertices`
return signature. Also reformat source and examples for consistency
and rebuild manual.pdf.
