    9797'''[/browser/trunk/Source/WebCore/platform/graphics/texmap/GraphicsLayerTextureMapper.cpp GraphicsLayerTextureMapper]''' is the glue between [/browser/trunk/Source/WebCore/platform/graphics/GraphicsLayer.cpp GraphicsLayer] and TextureMapperLayer. Since TextureMapperLayer is thread-safe and GraphicsLayer is not, GraphicsLayerTextureMapper provides the necessary glue. GraphicsLayerTextureMapper does not do anything interesting in particular apart from synchronization.

    99 '''[/browser/trunk/Source/WebCore/platform/graphics/texmap/TextureMapperBackingStore.cpp TextureMapperBackingStore]''' is what glues TextureMapperLayer with different backing stores.
     99'''[/browser/trunk/Source/WebCore/platform/graphics/texmap/TextureMapperBackingStore.cpp TextureMapperBackingStore]''' is the interface that glues TextureMapperLayer with different backing stores.
    100100It allows the type of backing store to be abstracted away from TextureMapperLayer, allowing TextureMapperLayer to be used both with a standard tiled backing store for WebKit1 (TextureMapperTiledBackingStore), a GraphicsSurface-backed backing store for WebGL (TextureMapperSurfaceBackingStore) or a backing store for WebKit2 (WebKit::CoordinatedBackingStore).
