TilingPath had some bugs when working with single-point segments, which exist outside of the official mods. This change fixes a few problems: - Avoid unbounded length zero-cost, zero-progression loops that could be formed by an arbitrary number of single-point corners. These could pop up arbitrarily in the middle of paths. - Avoid zero-progression loops short-circuiting looped paths. - Fix missing end type matching during back-tracing stage. - Enhance lint check to ensure starts/ends have a valid directions. - Remove some dead code.
