- Symbol querying is now global instead of per-tile - Symbols that bleed over tile boundaries no longer missed in queries - Symbol results now sorted based on rendering order (ie overlapping symbols change their sort order when a bearing change causes their render order to change) - Placement::retainedQueryData now responsible for maintaining symbol querying data for buckets that may no longer be in the TilePyramid.
