SSAO issue: non-occluded pixels

[Gianluca Tomasello]

non-occluded pixels are fixed on the screen when moving the camera. (pixels position depends on window size and resolutionScale)

Here is a state to hopefully reproduce ( my window size was 2370x1292 ):

Note that changing the window size will make pixels appear on other random places. I suggest to use right click pan to move the view and spot them on darker areas.
