VideoLayerChromium needs to be refactored to not access layerRenderer() or layerRendererContext().  The only GC3D that should be accessed is during updateCompositorResources.

This also means that resource deletion (via the destructor, for example) needs to be deferred until the next commit as the GC3D is not immediately available.  I'm not sure of the best way to do this.  These texture IDs need to be put on a queue either in the TextureManager or perhaps via some out-of-band message to the compositor thread.
