With the instantiatable ClutterShaderEffect, the only reason for ClutterShader to exist is to make the ClutterActor::paint implementation miserable. Yes, ClutterShader doesn't use a FBO, so it's "more efficient" on ClutterTextures. It's also generally wrong unless you know *exactly* how the actor's pipeline is set up — something we cannot even guarantee internally unless we start doing lame type checks.
