Bug 87567 – [BlackBerry] Add an Overlay layer

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit BlackBerry

[Arvid Nilsson]

The overlay layer allows us to have compositing layers even though the
            web page is not currently using accelerated compositing.
    
            These layers can be used to implement tap highlight, inspector overlay
            and more.
    
            Reviewed by Filip Spacek.


            The WebCore changes support the overlay layer functionality in WebKit
            by making it possible to add animations from the compositing thread
            without them being instantly overwritten during the next commit.
    
            Also a new custom layer type is added, which allow an overlay layer to
            draw itself using raw OpenGL calls. An instance of a custom subclass of
            LayerCompositingThread must be provided when creating the
            LayerWebKitThread. Then, the custom layer can be used as the content
            layer of a GraphicsLayer, or by itself.

It gets a lot better - there's a whole series of upcoming "overlay" patches to create a public BlackBerry::WebKit::WebOverlay API for adding AC layers to the web page =)
