bool QSGNodeUpdater::isNodeBlocked ( QSGNode * node,
QSGNode * root ) const
virtual

Returns true if node is has something that blocks it in the chain from node to root doing a full state update pass.

This function does not process dirty states, simply does a simple traversion up to the top.

The function assumes that root exists in the parent chain of node.
