Could you elaborate the semantics of applying a shader to, say,
ClutterGroup or the stage?

Since shaders are bound to painting vertex shaders obviously won't
affect clutter's idea of bounding boxes and such. Similar to scaling I
suppose, though I can't recall it being explicitly mentioned. Might be
worth documenting how different things are (not) related.

(I'm wondering whether shaders would be useful for implementing "full
scene" effects such as blurring half/whole stage simulating a glass
plate.)
