Surprised that this:
1) is needed.
2) is needed every time.
3) is harmless from a side effect point of view

FloatRect& destination)
Annoying that this repeats the code from the non-CG version. Is there a better
way to factor this?

> + player.setVisible(true);
Ditto.
> Source/WebCore/platform/graphics/displaylists/DisplayListItems.cpp:1242
> + // Should be handled by the delegate.
Ugly but OK.

> + static Ref<PaintFrameForMedia> create(MediaPlayer& player, const
FloatRect& destination)
Should not inline this kind of function. The constructor can get inclined
instead. Better for efficiency and for class definition brevity.

> + static Ref<PaintFrameForMedia> create(MediaPlayerIdentifier identifier,
const FloatRect& destination)
Ditto.
