case class BufferTile(sourceTile: Tile, gridBounds: GridBounds[Int]) extends Tile with Product with Serializable
When combined with another BufferTile the two tiles will be aligned on (0, 0) pixel of tile center. The operation will be carried over all overlapping pixels. For instance: combining a tile padded with 5 pixels on all sides with tile padded with 3 pixels on all sides will result in buffer tile with 3 pixel padding on all sides.
When combined with another BufferTile the operation will be executed over the maximum shared in
Behaves like a regular tile within the gridBounds. The access to the buffer is achieved through the direct access to the sourceTile or via the mapTile function that maps over the sourceTile.
