Subject: [PATCH] inline GluHalfEdge.dst manually before compilation

Closure Compiler won't do this since it's not a 'simple' getter, and V8 doesn't consistently inline at run time. This change is performance neutral on complicated polygons, but saves up to ~5% on streams of very simple polygons due to elimination of function call overhead.
