. the massive renaming undertaking: camelCase functions -> PascalCase. . add some cppdoc. . minor additional renaming improvements: e.g. GetIsClosed -> IsClosed . in entity code, replace constructs like "pvec = new vector; return pvec; use *pvec; delete pvec" with a simple stack variable passed as output parameter (avoid unnecessary dynamic allocs) . timer: simpler handling of raw ticks vs normal timer (less #if) This was SVN commit r5017.
