+ * These values can be used as a example for repaints throttling.
+ * 0,     0,   0,    0    - default WebCore's values, these do not delay any repaints
+ * 0.025, 0,   2.5,  0.5  - recommended values for dynamic content

+ * @param deferred_repaint_delay a normal delay
+ * @param initial_deferred_repaint_delay_during_loading negative value would mean that first few repaints happen without a delay
+ * @param max_deferred_repaint_delay_during_loading the delay grows on each repaint to this maximum value
+ * @param deferred_repaint_delay_increment_during_loading on each repaint the delay increses by this amount
