> It is difficult to apply ShareableBitmap client pattern to CoordinatedSurface because when CoordinatedTile requests for GraphicsContext, the GraphicsContext is modified in WebCoordinatedSurface and UpdateAtlas. Then, CoordinatedTile modifies this GraphicsContext (translate and scale), and then passes to TiledBackingStoreClient for actual painting. Therefore, it is really hard to apply this client pattern.

After a discussion with noam, I will try this client pattern.
