These should be private. For example, if anyone calls isVideo() on a RenderVideo you want the compile to fail so they don't create unneeded dead code.

Of course, most of the other virtual functions should be private too for the same reason.

Are those extra virtual calls in isSelfPaintingLayer() getting out of hand?
