Redefines the setf method for the pixels of the image class to the
correct order, and also re-defines coordinate as a single-float. Both
work for me and have been used with the examples with no observed ill -
effects.

Tested with recent cmucl (19c)

Note that the patch contains rather more than just the fix to (setf
image-pixel).
