There are isNeedsLayout() and needsLayoutProperty() and they might
give Node-based information whether the the layout and thus the
styling was applied. I guess this might be true, since doCSSPass() is
called before doLayoutPass() in the JavaFX thread, but could be wrong
on this regard.
As another (more fuzzy) option you could place a custom Logger into
PulseLogger and handle calls to the newPhase() method. The problem is,
that it only gives Scene-based information, i.e. you don't see which
Node was processed, so it might be unreliable information. I use a
custom PulseLogger for performance tests.
