Especially since this bit hasn't been coded yet. I think Cyrille is right 
though: the order ought to be:

content (flakes for KWord, rendered layerstack for Krita)
grids, rulers, guides, meshes, nets, selection masks
tool decorations

One thing that worries me a bit is the OpenGL here. I know that 
KoCanvasController will draw its thing using QPainter, and that that works 
fine for Qt's OpenGL widget. But if there are cool things that can be done 
using OpenGL but cannot be done using QPainter -- where do we do that? Maybe 
we'll need to add some hooks or something for that, later, when we need it.
