How about OnRasterCompleted() and OnRasterTaskCompleted() instead and only refer
to work posted to the worker pool as tasks?

[Sami, 2013/02/05 12:26:23]

Good idea, I like that naming.

   void DidFinishTileInitialization(Tile* tile);
   void DidTileRasterStateChange(Tile* tile, TileRasterState state);
   void DidTileBinChange(Tile* tile,
                         TileManagerBin bin,
                         WhichTree tree);

Maybe rename to PerformRaster if you like my suggestion above.

[Sami, 2013/02/05 12:26:23]

Done.
