An ImplAnimView is actually just a way of rendering an animation to an
OutputDevice (RenderContext). Each instance has a unique ID (called
mnExraData, which is quite misleading). ImplAnimView doesn't really
mean much so hence the rename to make this a bit more clear.
In the process, also rename local variables pView to pRenderer in
Animation functions.
