/**
 * @class pqAnimationProgressDialog
 * @brief progress dialog for animation progress
 *
 * pqAnimationProgressDialog is a QProgressDialog that hooks itself up to
 * monitor (and show) progress from an animation scene. The dialog uses the
 * cancel button to abort the animation playback.
 *
 * Typical usage:
 *
 * @code{.cpp}
 *   pqAnimationProgressDialog progress(
 *   "Save animation progress", "Abort", 0, 100, pqCoreUtilities::mainWidget());
 *   progress.setWindowTitle("Saving Animation ...");
 *   progress.setAnimationScene(scene);
 *   progress.show();
 *
 *   auto appcore = pqApplicationCore::instance();
 *   auto pgm = appcore->getProgressManager();
 *   // this is essential since pqProgressManager blocks all interaction
 *   // events when progress events are pending. since we have a QProgressDialog
 *   // as modal, we don't need to that. Plus, we want the cancel button on the
 *   // dialog to work.
 *   const auto prev = pgm->unblockEvents(true);
 *
 *       // ---- do animation playback ---
 *
 *   pgm->unblockEvents(prev);
 *   progress.hide();
 * @endcode
