Well, depends on what you call a layer tree. Currently a layer tree is mostly a tree of intermediate surface that you render into, right? It's not a tool describe the content you want to rasterize (with the exception of color layers). Our layer tree is about where you rasterize content rather than how (mostly). The gtk folks call the layer tree they are working on a scenegraph (but honestly I wouldn't call it that) so I suppose we need to be sure we talk about the same things. If a layer tree starts having things like shape layers, text layers, etc. then it becomes closer to what I call a scenegraph.
