+This optimization makes QProgressBar::setProgress() only repaint itself if
+stepping to the new progress would cause a graphical change. This means
+that for a width W and a total number of steps S, it will repaint itself
+'W' times (every 'S/W' steps) instead of 'S' times (every step) as it is right
+now.
