pub fn new_web_mercator() -> Self

Create a new map grid using web mercator coördinates.

pub fn srid(&self) -> i32

Get the spatial reference ID.

pub fn bbox(&self) -> BBox

Get the bounding box of the grid.

pub fn tile_bbox(&self, tid: TileId) -> BBox

Get the bounding box of a tile ID.

pub fn tile_transform(&self, tid: TileId) -> Transform

Get the transform to coördinates in 0 to 1 range.
