For instance, like it is done in the “threadedanimation” example: https://qt.gitorious.org/qt/qtdeclarative/source/817cd03a5f437c9e8862646cca5ea016b1223bc7:examples/quick/scenegraph/threadedanimation <https://qt.gitorious.org/qt/qtdeclarative/source/817cd03a5f437c9e8862646cca5ea016b1223bc7:examples/quick/scenegraph/threadedanimation>

This is correct, you are limited to animation inside the subtree you returned from updatePaintNode().
