Window peep events

Added more window_peep_events.
In the process noticed a mistake in clip dpi.
Also generalised one of window_parks functions as it was basically the same in window_peep.
I've disabled my peep_draw function for now and this will cause a graphical glitch when resizeing the window.
I'm away on holiday for a week so I will not be making any more additions until I am back.
