Why 'generate'? Why not just plugInStartButtonImage() ?

> Source/WebCore/rendering/RenderSnapshottedPlugIn.cpp:138
> +    if (initializedImages[arrayIndex])
> +        return 0;

Is this just to avoid multiple aborted attempts to get the image? Do we expect that ever to happen?

> Source/WebCore/rendering/RenderSnapshottedPlugIn.cpp:154
> +    Image* buttonImage = 0;
> +    if (plugInImageElement()->hovered())

This logic is a bit odd. Why not just early return if not hovered?

I'm not sure why you have to run this logic at layout time. Can't you just choose what to paint at paint time?

Renamed. This was originally connected to the idea that via the WK2 API we have to copy the data to a bitmap image every time we make this call, but since the code already caches those images, this is less important.

If a client decides not to provide an image, then we will already ask for it. So I wanted to avoid that. Clients that implement this probably will provide all buttons.

Yes, I've updated the logic here.

I thought it might be less performant to do this on every paint, but I can move it. Moving it would also obviate the need for these instance variables.
