            Update WebPageCompositor::render() API
            RIM PR #151887
    
            Now we have a clearer picture of what parameters need to be available
            in order to render the web page.

            Plumb through new WebPageCompositor parameters to LayerRenderer
            PR #154334
    
            The new API allows the embedder to specify the root transform and many
            OpenGL related parameters to be used when rendering the web page.
    
            To honor the transform, we have to implement a way to composite the
            BackingStore output using a generic transform. This method,
            BackingStorePrivate::compositeContents(), uses a strategy that differs
            from blitContents(), because that one is optimized for software
            blitting, while this one is optimized for GPU rendering. Specifically,
            instead of drawing the checkerboard first, and the rendered subregions
            of the tile afterward, we draw the whole tile in one call, and then
            draw checkered regions on top, if any.
    
            Removed the blit generation condvar from the new code paths for drawing
            BackingStore output using a transform, since the condvar is ineffective
            in preventing flicker when we're not in charge of swapping the window.
            Instead, another synchronization solution will be implemented in the
            future.

            The new API allows the embedder to specify the root transform and many

            Also refactor the code to allow several sets of layers to be rendered,
            and to allow interleaving the rendering of layers with rendering of
            buffer and checkerboard.

Looks good.

Could combine with above if.

> Source/WebCore/platform/graphics/blackberry/LayerRenderer.cpp:325
> +    for (size_t i = 0; i < sublayers.size(); i++) {

might want to stick to always using ++i or i++, now it is inconsistent.

> +        float opacity = 1;

I am not sure this extra var is needed.
