Architecturally, I'd be fine with the assumption that we call appendQuads prior to any draw call.  That would let you push all the io surface handling back into plugin layer, and simply give the quad a texture id.

You could create one during PluginLayerChromium::updateCompositorResources, store it on the PluginLayerChromium, and sync it over to the CCPluginLayerChromium.  That's the path where all the other texture ids gets allocated.
