Type: Optical Margin Alignment hangs punctuation at the ends of type on a path

Optical Margin Alignment and Roman Hanging Punctuation hung punctuation in point and area type only. Type on a path kept its first and last glyphs inside its brackets with either option on. When Optical Margin Alignment is on, or the first paragraph has Roman Hanging Punctuation on, the glyphs at the ends of left-to-right type on a path now hang outside its brackets by the same amounts, measured along the path. The type hangs at the start bracket when its line is placed there, hangs at the end bracket when the line is placed there, and hangs at both when it is centered. Glyphs that hang past the end bracket do not make the type overflow. On an open path a hang stops at the path's end, and on a closed path the two hangs together take at most the stretch between the end and start brackets. SVG export writes type on a path that hangs as outlines, with a warning. Docs: docs/mcp.md, docs/type-parity.md, docs/target-app-parity.md.
