 CoordinatedGraphicsLayer does not deal with IPC directly. Instead, it saves the information gathered from the compositor, and prepares it for serialization. It maintains an ID for each layer, which allows naming each layer, links a layer ID with its backing store, and deals with directly composited images and how they are serialized.

 '''[/browser/trunk/Source/WebKit2/Shared/ShareableSurface.cpp ShareableSurface]''' is a glue class that abstracts away the differences between GraphicsSurface and ShareableBitmap for the purposes of serialization. This is a convenience, to allow us to avoid adding #ifdefs or special code-paths for GraphicsSurface in too many places in WebKit2.
 
-'''[/browser/trunk/Source/WebKit2/UIProcess/CoordinatedGraphics/CoordinatedBackingStore.cpp CoordinatedBackingStore]''' synchronizes remote tiles (created by the TiledBackingStore) and ShareableSurfaces with TextureMapper in the UI process. It is responsible for copying or swapping the data in the BitmapTexture with new data or updates from ShareableSurface. It also knows how to paint the different tiles with relation to the parameters received from TextureMapperLayer.

-'''[/browser/trunk/Source/WebKit2/WebProcess/WebPage/UpdateAtlas.cpp UpdateAtlas]''' is a graphics-memory optimization, designed to avoid fragmented allocations of small update buffers. Instead of allocating small buffers as it goes along, UpdateAtlas allocates large graphics buffers, and manages the update-patch allocations by itself, using square shapes inside the large buffers as sub-images to store temporary pixel data.
