If you’re going to touch all these loops, then you should clean them up even more using C++11 syntax and the functions like keys() and values() for simple iterations of maps. Example:

> Source/WebCore/platform/graphics/TiledBackingStore.cpp:118
> -    TileMap::iterator end = m_tiles.end();
> -    for (TileMap::iterator it = m_tiles.begin(); it != end; ++it) {
> +    for (auto it = m_tiles.begin(), end = m_tiles.end(); it != end; ++it) {
>          if (!it->value->isDirty())
>              continue;
>          dirtyTiles.append(it->value);

for (auto& tile : m_tiles.values()) {
        if (tile->isDirty())
            dirtyTiles.append(tile);
    }

> Source/WebCore/platform/graphics/texmap/coordinated/CompositingCoordinator.cpp:239
> +    for (auto iter = m_imageBackings.begin(), end = m_imageBackings.end(); iter != end; ++iter)
>          iter->value->update();

for (auto& backing : m_imageBackings.values())
        backing->update();

> Source/WebCore/platform/graphics/texmap/coordinated/CoordinatedBackingStore.cpp:82
> +    for (auto it = m_tiles.begin(), end = m_tiles.end(); it != end; ++it)
>          m_tilesToRemove.add(it->key);

for (auto& key : m_tiles.keys())
        m_tilesToRemove.add(key);

> Source/WebCore/platform/graphics/texmap/coordinated/CoordinatedGraphicsScene.cpp:563
> +    for (auto it = m_backingStoresWithPendingBuffers.begin(), end = m_backingStoresWithPendingBuffers.end(); it != end; ++it)
>          (*it)->commitTileOperations(m_textureMapper.get());

for (auto& store : m_backingStoresWithPendingBuffers)
        store->commitTileOperations(m_textureMapper.get());

I used the more C++11 syntax to clean-up for loops by your guide. Thanks Darin.
