* Fixed NaN on normalize 0 vector. * Tentative implementation in getStepLength. * mapEntity.TileX/Y removed. * Fixed Position and Target not being initialised in createMapEntity. * mapEntity.Position is no longer embedded. * mapEntity.LocationX/Y no longer used outside map_entity.go. * mapEntity.subCellX/Y removed. * mapEntity.LocationX/Y removed. * mapEntity.OffsetX/Y and TargetX/Y removed. * Direction method added to Vector, returns 0-64 direction. * Moved Vector.Direction() to Position.DirectionTo and refactored. * Renamed RenderOffset from SubCell and tested IsZero. * d2math.WrapInt added for use with directions. * Tidied up position and tests. * Refactored d2common.AdjustWithRemainder into d2mapEntity. * Tidying up d2mapEntity. * Final cleanup. * Lint warnings. * Spelling correction.
