Class TileDebug

Classdesc

A pseudo tile source, which does not fetch tiles from a server, but renders a grid outline for the tile grid/projection along with the coordinates for each tile. See examples/canvas-tiles for an example.

Uses Canvas context2d, so requires Canvas support.

Param: options
