Has anyone else seen this problem, or does anyone have any idea what's
wrong.....

I'm putting an icon on the screen by copying a pixel array point by
point into a window with:

  (setf (xlib:gcontext-foreground gc) pixel)
  (xlib:draw-point window gc (+ x sx) (+ y sy)).

The x and y are correct as is the value of the pixel.    Everything is
being drawn correctly.   But the colors I'm getting are totally wrong.
  This code was working until I updated SBCL to 0.9.4 and CLX to 0.7.3.
   Am I missing something or is this a bug?
