+ * XXX: We send OnCommand on load, then we send no updates until we get
+ * StartTransitioning.  Historically, this was fine, but it's incorrect now
+ * that commands can have arbitrary side-effects.  We should only send OnCommand
+ * when we get StartTransitioning, but we need to run it early to set m_fLengthSeconds.
+ * Eventually, phase out GetLengthSeconds (ScreenGameplay is somewhat tricky).  For
+ * now, play a "StartTransitioning" command; put anything that has side-effects in
+ * there, instead.
