-dynamic scene, don't set duration on running animation (doesn't work)
-dynamic scene, just use set colors instead of system palette (in case
platform doesn't support it right, like N900)
-dynamic scene, calculator and shadereffects, don't rely on root item being
automatically in scope (possibly confusing)
