Fading MouseTrails

-----------------------------------

I made a Mouse trail but I need help trying to fade it so we can see the background.

This is what I have so far:
procedure MouseTrail

    var x, y, oldx, oldy, b : int := -1
    var c : int := 0
    loop
        % Get the current location of the mouse
        mousewhere (x, y, b)
        % if the mouse has moved and the button is pressed.
        if (x not= oldx or y not= oldy) then
            % Draw a circle around the mouse location
            drawfilloval (x, y, 8, 8, c)
            % Change the color
            c := (c + 1) mod 16
            oldx := x
            oldy := y
        end if

    end loop


end MouseTrail

Fading is actually pretty difficult in Turing. The easiest method I think is to use transparent gif images instead of drawing ovals.

As insectoid said, fading is difficult. Something not quite as difficult (still not easy) would be to do what Windows does for mouse pointer trails and only show the last few mouse pointers.
