     - signal based?
   - ShaderEffectItem
     - Use source to grab static image of subtree for later use
+    - Be able to feed the texture output into an Image element
     - Feed arbitrary texture values into shader effects?
+    - Change ShaderEffectSource to be more of a TextureAbstraction and
+      add things like grab(), texture id, etc to it so that it more
+      easily can be passed around and used for stuff... ShaderEffectItem
+      then becomes just one of several places where it can be used...
+    - Make effects using same source code use the same ShaderProgram
   - Adaptation layer plugin infrastructure?
   - Outstanding bugs:
     - Vsync driver never pauses
