[GTK] Implement iframe shim technique for windowed plugins in WebKit2

• Component: WebKit2
• Status: RESOLVED CONFIGURATION CHANGED

[Carlos Garcia Campos]

It allows to show iframes on top of a windowed plugin. This is covered by layout test plugins/iframe-shims.html that for some reason works when run with WTR. It seems than the fake mouse events used by WTR reach the buttons that are hidden. This doesn't happen when running the test manually.

GTK+ bits look good to me.

> Source/WebKit2/WebProcess/Plugins/PluginView.cpp:1027
> +static bool iframeIsAbovePlugin(const Vector<const RenderObject*>& iframeZIndexStack, const Vector<const RenderObject*>& pluginZIndexStack)
> +{
> +    for (size_t i = 0; i < iframeZIndexStack.size() && i < pluginZIndexStack.size(); ++i) {
> +        // The root is at the end of these stacks. We want to iterate root-downwards so we index backwards from the end.
> +        const RenderObject* iframeStackRootObject = iframeZIndexStack[iframeZIndexStack.size() - 1 - i];
> +        const RenderObject* pluginStackRootObject = pluginZIndexStack[pluginZIndexStack.size() - 1 - i];

This requires preserving the original copyright, I think.

Can we use a region instead of a list of vectors for occlusions?

Yes, indeed.

r-, as this has been pending review for over a year now. It is near-impossible that this patch still applies to trunk and unlikely to still be relevant in its current form.
