Kazimir,

Pixel(x,y,1,1) is not too awful under Windows, but under UNIX you'd
probably want to code things up differently

every x := 0 to width-1 do
   every y := 0 to height-1 do {
       p := Pixel(x,y,1,1)
       do_stuff(p,x,y)
       }

is a LOT slower (especially under X11) than the single call to the generator

x := y := 0
every p := Pixel() do {
   x +:= 1; if x = width then { x := 0; y += 1 }
   do_stuff(p,x,y)
   }
