Tile is now the main base class; RasterTile, VectorTile, etc are its subclasses. GeometryTileData and its subclasses form the piece that's passed to the worker.
The keys in the vector tile may not be in alphabetical order. Building a vector of keys by looping over std::map<std::string, …> effectively sorts the keys by alphabetical order without sorting the associated values. This change inserts keys in the same order in which they appear in the vector tile.
Previously, vector tile coordinates were being normalized to util::EXTENT in each place they were used, and for annotation and GeoJSON sources that don't require normalization.
